Wheel of Fortune timeline (network)

An incomplete timeline for the daytime Wheel of Fortune. As daytime did not use seasons, and since the show debuted in January, this timeline is divided by year. For the nighttime version, see Wheel of Fortune timeline (syndicated).

(Due to practices of the era and Merv Griffin Productions, most episodes from 1975-85 were destroyed or recorded over; a survival list is here. Further, Game Show Network {henceforth referred to as GSN} has only shown three daytime episodes. As a result, this timeline will be much less detailed than the nighttime one.)

Pilots (1973-74)
September 1973 :
 * Sometime this month, the Shopper's Bazaar pilot is taped for NBC by request of Lin Bolen to Merv. The very first attempt at the format, it is markedly different from the eventual series in various ways:
 * The show is hosted by Chuck Woolery, with announcer Mike Lawrence. Two female models are also present (one Caucasian, the other African-American), but they do not appear after the opening segment and are not listed in the credits; the latter is believed to be Harriet, a model who appeared in the earliest nighttime episodes of The New Price Is Right the previous year.
 * Bill Carruthers is both producer and director.
 * The main theme is an instrumental version of "Chitty Chitty Bang Bang" (1968), by Richard M. Sherman and Robert B. Sherman. The cue used for commercial outros and the post-Round 4 prize tally is an instrumental version of "Spinning Wheel" by Blood, Sweat & Tears (released in 1969).
 * The Wheel, designed by Ed Flesh and based heavily on those used in various casinos, is vertical and mechanical (although Spencer Davies is credited as Art Director). ShoppersBazaarRound3Wheel.jpg
 * There are two Lose A Turn wedges (with two more added for Rounds 3-4) plus one each of Free Spin, Buy A Vowel, Free Vowel, and Your Own Clue. Cash amounts range from $0 to $500 (in Rounds 1-2) or $1,000 (Rounds 3-4).
 * Landing on Free Spin gives that player a thin white disc with "Free Spin" in black on a yellow background, which may be turned in if that player calls a wrong letter or lands on Lose A Turn.
 * Despite the presence of Buy A Vowel, contestants may buy vowels at their discretion for $250.
 * The Wheel is halted by Chuck pressing a button once the player in control yells "Stop the Wheel!", which makes the arrow above the Wheel come into contact with the spokes (although the Wheel occasionally resumes spinning almost immediately after stopping).
 * The opening layout has no penalty wedges nor $0 spaces, and a top value of $450. ShoppersBazaarPuzzleBoard.png
 * The puzzle board is brown, with three rows of 15 spaces each and letters (in the Hopkins font, also used for the logo) revealed by pull-cards, with a staff member clearly visible behind it; a fourth row serves to denote letters that are called but not in the puzzle.
 * Correct and incorrect letters are denoted by an electronic-sounding bell and buzzer; the latter is also used for Lose A Turn, while a set of six bells notifies the players when only vowels remain. The player who solves the puzzle has the privilege of going first in the next round. ShoppersBazaarWideSetShot.png
 * Only three categories are used: Person, Place, and Thing. While Chuck brings this up at the start of each round, the specific category is only given through Your Own Clue.
 * The set resembles an antique store, with the prizes strewn about along with other items (including picture frames on the back walls) and wood paneling. Chuck's area is a thin podium with an angled surface. The contestants, all female, sit at individual chairs behind a short table (a single three-cushion couch during the opening segment). The table itself has a white rotary phone on top, which is used for Your Own Clue.
 * The opening begins with a close-up of the Shopper's Bazaar logo as Lawrence says "You are at the Shopper's Bazaar. These ladies [Marilyn, Dawn, and Maureen] have been shopping and selecting gifts from our boutique to play for in our game today." The contestants are introduced one at a time, and Lawrence gives a brief description of the three prizes she has selected followed by her grand total; following this, Chuck asks her to stop the Wheel, and once it does she picks a consonant for the Round 1 puzzle.
 * The process repeats with the other two players, with the back of the set splitting apart (and the logo raising up) to reveal Maureen's last choice: a 1974 Pontiac Firebird. After the third letter call, Lawrence says "That's how our game is played! And now, here is the host of the Shopper's Bazaar: Chuck Woolery!" Vlcsnap-00008.png
 * Prizes and contestant winnings are handled by an "Accounting Department", an offstage board of three columns with four squares each which lists the three prizes each contestant chose before the taping and their values; below these cards are flip displays showing how much that player has earned toward winning it, while above the top prize is each player's name and the total value of their prizes. While all three players' money carries over from round to round, with winnings being applied to the next prize once one is covered, a contestant can only "bank" the money if she solves a puzzle; should she do so and have enough to buy a prize, she wins it (a star appears on the far right of that prize's flip display, and the square itself is lit up much). The board is shown on-camera after each round to update the scores.
 * Contestants who do not win any prizes receive a Magnavox black-and-white TV as a consolation prize.
 * The winner (determined by how many prizes she wins, not how much money she accumulates) plays a bonus puzzle called "Shopper's Special": the player is shown all vowels in the puzzle (also the name of the prize she is playing for), then has 30 seconds to give one correct consonant and solve the puzzle. The timer cue is Merv's "A Time For Tony", cued up at the 1:20 mark (appropriately, a ticking section). An unknown cue is used while the bonus prize is described. MervGriffinProdslogo1973.png
 * The credits, also in the Hopkins font, scroll vertically with the name in all-caps below their credit. The credit roll ends with the Merv Griffin Productions logo, albeit an entirely new design rather than the one then in use on Jeopardy!: a transparent white vertical rectangle with rounded edges, containing a drawing of a griffin over "MERV GRIFFIN productions", which is superimposed on the spinning Wheel for the last few seconds. This version, also used on the subsequent two pilots, becomes the company's main logo in 1975 and remains (with minor adjustments) through November 25, 1983; the griffin itself is retained until around 2009.
 * There are no fee plugs, sponsor lists, eligibility disclaimers, or wardrobe credits.
 * On the pilot itself: 1973PilotSlate.pngShoppersBazaarR3SetComposite.jpgShoppersBazaarColor.jpg
 * In a departure from normal practice, the slate (a piece of poster board held by a stagehand in front of the on-set refrigerator/freezer combo) does not use a recording date, only saying "Shopper's Bazaar Pilot Show #1" with the show's title in quotation marks; it is very likely there were no subsequent tapings, as explained below.
 * The very first puzzle is HENRY KISSINGER, who was sworn in as Secretary of State on September 22, 1973; this would suggest that Bazaar was taped within a few days of the event.
 * The first wedge landed on is $100, and the first letter revealed is S. The first "dud" is T, which does not appear in any of the puzzles.
 * As Maureen is introduced in the opening, she is shown next to a clock displaying a time of 6:40.
 * The first vowel bought is I, by Marilyn in Round 1; however, only $150 is deducted from her score.
 * During Round 2, as Maureen debates over what to do, Chuck says "Quickly, or we'll be into Search for Tomorrow." despite the fact that it airs on CBS at this point (although it moves to NBC in March 1982). Amusingly, one player says "Search for Tomorrow?" a few seconds after Maureen opts to stop the Wheel, to which Chuck replies "I don't know."
 * Marilyn lands on Free Spin in Round 3, but continually opts to save it. She ends up losing the game.
 * After the Round 4 puzzle is solved, the stagehand behind the puzzle board accidentally pulls up the last letter card while revealing it.
 * Lose A Turn and Free Vowel are hit four times each. Interestingly, Buy A Vowel is not hit.
 * Although $0 is hit three times, no correct letters are called for that amount.
 * Following the Shopper's Special, Chuck says that there will be three new players "tomorrow". Papers detailing the Bazaar format mention returning champions, although why this element was dropped is unknown.
 * When shown to test audiences, the response is that of unenthusiasm: they do not understand the gameplay nor why players have to buy vowels, and cannot see the puzzle board. The viewpoint is shared by Bolen (who called Bazaar "old-fashioned") and Griffin (who simply said that "Everything about it was wrong."). A further problem is that discounting the slate, the pilot runs a staggering 30½ minutes, and there is no indication that the show was intended for anything larger than a half-hour slot.
 * Prior to May 30, 2012 (when the opening segment surfaced), Bazaar had been represented by approximately four publicity shots (one in color) over the years, including the show's E! True Hollywood Story; further, while GSN holds a copy and has aired numerous pilots over time, they have not yet shown Bazaar. These may be due to the use of "Chitty Chitty Bang Bang" and/or "Spinning Wheel".

August 1974 :
 * On August 28, the second and third pilots (now called Wheel of Fortune) are taped in Burbank for NBC. Changes include:
 * Edd Byrnes and Charlie O'Donnell replace Woolery and Lawrence.
 * The show's theme song is changed to "Give It One" by Maynard Ferguson, from his 1972 album M.F. Horn Two.
 * The Wheel is redesigned by Flesh to be horizontal and spun by the contestants (using the pegs), with much larger wedges. Free Vowel, Your Own Clue, and $0 are retired, while Lose A Turn is pared down to just one wedge and Bankrupt is introduced. The minimum is increased to $25, and the top amounts are changed to $350 for Round 1, $500 for Round 2, $750 for Round 3, and $1,000 for Round 4. The chroma-key center of the Wheel is green, but changes color for every spin.
 * While the wedges are still separated by pegs and black lines, each individual wedge now has two pegs in the middle, dividing them into thirds.
 * The font for the dollar signs, numbers, and letters are changed to Fortune Extrabold (also known as Chesterfield).
 * The "pointers" (see below) are flimsy, and as a result the Wheel is extremely loose, despite a prop man being underneath (lying on his back with a TV monitor nearby); the prop man nearly faints from this, resulting in the inclusion of air conditioning and a fan.
 * Buy A Vowel is added in Round 2, with a second wedge added in Round 3. A second Bankrupt and another Lose A Turn are added for Round 4, replacing Free Spin in the process. All four special spaces have white outlines, and all except Bankrupt have white outlines around the letters. PuzzleBoard82874.png
 * The puzzle board is also redesigned by Flesh to be much larger and gray, with 39 trilons on three rows and a single light border, a prop which slides onstage at the start of each round. The trilons show green sparkles for unused spaces, a solid white for unrevealed letters, and black letters on a white background. Correct and incorrect letter calls are signified by a ding and buzzer, respectively; correct letters light up the border plus all of that letter's instances at once.
 * In the event that only vowels remain in the puzzle, eight high-pitched beeps are heard.
 * Once a puzzle is solved, all unrevealed letters light up and turn around to a portion of "Give It One". As with Bazaar, the player who solves the puzzle spins first in the next round.
 * While the puzzle board is designed to be motorized, this element is not completed by the time of taping. A portion is finished, but these are gutted out so the trilons can turn freely; Susan Stafford is hired to turn the letters.
 * Edd notes at the beginning of the game that each puzzle is a Person, Place, or Thing, then gives a clue for each round (for instance, the first puzzle of Pilot #3 is "a popular television actor").
 * The host/contestant area is overhauled: ContestantArea1974.jpg
 * The players now stand. Behind them are three pillars with the same green sparkles as the unused trilons and a white display showing money put "on account" (with an "ON ACCOUNT" light above the display) or total winnings for champions. The display shows up to four digits plus a dollar sign, omitting the latter for winnings of $10,000+.
 * A white railing is in front of the players and host at about hip level, which is curved around at the host's area. Attached to the railing at the host's area is a stack of Free Spin discs, which are now tan with "FREE SPIN" written in white characters in the middle.
 * Below the railing at the contestant area is a set of three black displays used to denote score during puzzles and cumulative totals after Rounds 2+ (both in a white Eggcrate font), with the same limitations as the displays behind them. These main displays are placed above large arrows which flash for each contestant's turn, and at the end of each arrow is a thin, flat "pointer" used to slow the Wheel to a stop and denote what space that player has landed on (as noted above, they did little for the former). The arrows are red, yellow, and blue for the first, second, and third players respectively. 1974_Pilot_Shopping.png
 * Contestants now purchase from a "showcase" of prizes located behind the puzzle board, which moves away so the player can shop. Both pilots use the same prizes, with their names and values scrolling on the left side of the screen; a "SOLD" tag marks prizes already purchased.
 * After solving one of the first three puzzles, players may opt to put those winnings "on account" immediately or go shopping. Round 4 is always followed by shopping, with any remaining money likely placed on a gift certificate (as there is a gift certificate prop among the prizes).
 * An unknown cue plays as Charlie describes the shopping prizes.
 * The Wrong Letter Board and Accounting Department are combined into a single chalkboard with 26 flip-up cards on top. The cards are flipped back once a letter is called, becoming a true "Used Letter Board", while the chalkboard itself is used to show the players' names and keep track of both their current and cumulative scores (with a separate section denoting money put "on account"). The chalkboard, like the Accounting Department, is placed offstage; unlike the Accounting Department, the Used Letter Board is almost never shown on-camera. 1974Logo.png
 * The intro begins with Charlie mentioning several prizes as they are shown (specifically, "A spinet piano, a trip to Las Vegas, a Muskin Dune Cat, a 24-inch color TV, a 1975 automobile [more specifically, an Opel], or a Snark sailboat!"), followed by a wide shot which is chroma-keyed into a slowly zooming-out shot of the Wheel. Charlie continues with "These are just some of the many exciting prizes available. Total retail value of all these prizes: $20,130! Yours to buy today on Wheel of Fortune! And now, here's your host: Edd Byrnes!"
 * "Give It One" plays from the 2:33-3:10 period, with the last note of the song edited in.
 * As Charlie says "all these prizes", the money graphic (using a tall, thin font) appears.
 * At "host", the shot zooms back in through the Wheel as Edd walks out. He then introduces Susan, who walks up from the contestants' left holding an ECM-51 microphone and introduces the players as their backdrops light up (over another portion of "Give It One").
 * The final segment consists of Edd recapping the scores, announcing the winner, and talking briefly with Susan as an unknown cue plays. As they sign off, Edd spins the Wheel as it zooms back into view with the two in the center, and as "Give It One" plays from the beginning. The chroma-key shot, which moves over to the prizes, continues through the credits and as the Griffin logo appears.
 * Other notes about these pilots:
 * The Bazaar staff is replaced minus Flesh (now credited outright), John Lauderdale, and David S. Williger. John Rhinehart becomes producer, while Marty Pasetta directs. Among the production staff is Nancy Jones, who becomes co-producer with Rhinehart when Wheel debuts; a late-1986 interview suggests Nancy was also present for Bazaar, although she is not credited there.
 * Edd is drunk during these pilots, as he recounts in his autobiography Kookie No More. During both tapings, he says odd phrases like "Spin the puzzle and solve the Wheel." and generally makes it clear he is reading from cue cards. While he is noticeably more sober for Pilot #3, he is confronted after the taping by an upset Susan.
 * Oddly, while Edd changes suits between the pilots, Susan wears a single powder-blue outfit for both.
 * There are no fee plugs, sponsor lists, eligibility disclaimers, or wardrobe credits.
 * During the taping, Merv becomes upset that Pasetta includes shots of other things, demanding that Wheel be shot more like Jeopardy! Pasetta eventually retaliates to these demands, possibly between the pilots, by demanding that Merv be barred from the control room – a viewpoint shared by Bolen.
 * On Pilot #2 (Marge/Gary/Roseanne):
 * Edd makes faces at the camera at points during the taping, and during Round 1 mistakenly says the total of all the values is $435 rather than $4,225.
 * The first wedge hit on the new Wheel is $200, and the first letter called on the new puzzle board is the R. The first "dud" is T.
 * During Round 1, the board and sound operators both mishear Gary's call of F as S (a call repeated by Edd even after the S's are revealed), although this is not noticed.
 * In the same round, Gary calls a repeated T, but it is only acknowledged as a wrong letter.
 * Roseanne's nametag falls off on her first spin of Round 2. It disappears later in the round, but she does not wear it again until the start of Round 3.
 * Edd's hint for the Round 3 puzzle MOTHER GOOSE is "a fictional character", resulting in the debut of Fictional Character.
 * During Round 3, Roseanne opts to solve for $1,300 only to be bullied by Edd (yelling "No don't guess, it's too early! Look at all the money you can make, you can make thousands of dollars! Be a gambler!") into spinning again. She solves one turn later with only the T, H, and R showing.
 * During Round 4, after Marge hits $900 for the second time in a row, Edd tells her "I think you've fixed the Wheel!", an ironic statement given the show was using a prop man to stop the Wheel with his feet.
 * Shortly after the above, Marge is given $750 for two R's rather than the proper $700.
 * Oddly, neither Buy A Vowel nor Bankrupt is hit, and no vowels are bought.
 * Despite Marge being called the returning champion by Edd at the top of the show, no cumulative total is shown or mentioned in the final segment.
 * Losing players receive unstated parting gifts regardless of whether they solve any puzzles. Edd's phrasing suggests that the gifts are added to any prizes that are purchased during the game.
 * On Pilot #3 (Tanya/Frank/Lois):
 * The lighting is a bit darker during the opening, most noticeable on the overhead Wheel shot.
 * Edd makes noises as the Wheel spins, and during Round 1 mistakenly says the total of all the values is $4,335 rather than $4,225.
 * Tanya had previously been a model on The New Treasure Hunt the previous year. This is not surprising, however, as game show pilots have typically used actors or professional contestants to play the game.
 * During Round 1, Tanya is given $775 for three L's rather than the proper $675 due to a mathematical error by Edd. The display initially shows the proper score of $1,375, but is "corrected" to $1,475 almost immediately afterward.
 * Susan forgets to turn the last A in the Round 1 puzzle TELLY SAVALAS.
 * During the shopping portion of Round 1, Edd talks Tanya into buying a $660 brass bed.
 * Despite Tanya being called the returning champion by Edd at the top of the show, no cumulative total is mentioned in the final segment.
 * Following the full credit roll, Charlie says "Wheel of Fortune is a Merv Griffin production.", which he did not say at the end of Pilot #2.
 * When shown to test audiences, the response is that the new set is too busy, the sound effects are too noisy, and Byrnes does not fit. Bolen insists the show be picked up anyway, placing her job on the line: if Wheel fails, she leaves the network; if it succeeds, she gets a raise. Her bosses agree by November 18, but in early December the decision is made to replace Edd with Chuck, making the announcement on December 13. (It is rumored that Edd was caught reciting his vowels backstage by Merv.)
 * Clips of Pilot #2 were shown during the ceremonial 3,000th nighttime show on November 20, 1998, which claimed it was the pilot (disregarding Bazaar and #3).

1975
January 1975 :
 * Wheel debuts on January 6, replacing Jeopardy! as per contract in the 10:30 AM slot formerly held by Winning Streak. Other than Chuck hosting, the major changes are:
 * 1) The show's theme is changed to "Big Wheels" by Alan Thicke, who also supplies the show's other music cues.
 * 2) Jeff Goldstein replaces Pasetta as director.
 * 3) The format is slightly altered to use three Wheel templates, with the top values now being $500 in Round 1, $750 in Round 2, and $1,000 thereafter. The other values are also moved around a bit, with $225, $325, $375, and $425 being retired, Buy A Vowel now available from Round 1, Free Spin removed after Round 1, a second Bankrupt added in Round 2, and a second Lose A Turn and Buy A Vowel added in Round 3.
 * 4) The puzzle board trilons now turn clockwise instead of counterclockwise, and multiples of a letter light each instance one at a time. A four-note chime now plays at the start of each round.
 * 5) Each round's category is now given outright to the players and shown in large all-caps (in the Helvetica Bold font) below the puzzle, albeit sporadically due to being on art cards.
 * 6) The single shopping "showcase" behind the puzzle board is changed to three platforms at the back of center stage. The first platform is used after Round 1, the second after Round 2, and the third after Round 3; in the event of subsequent rounds, the process begins again at the first platform (or the first with prizes remaining).
 * 7) The platforms are behind a set of panel doors similar to those of Let's Make a Deal, inside a border that resembles the puzzle board (using a 10&times;5 grid of what appear to be square mirrors). The doors open after each round to reveal the prize platform for that round; once Charlie finishes describing the purchased prizes, the doors close and "hookers" (stagehands with large hooks) pull the platform out of the way and set up for the next round.
 * 8) The scrolling prize/value list is replaced by a set of price cards placed on or near the prizes; these cards use black characters on a white background. A photo showing these tags appears in the first issue of the show's Off Camera newsletter in 1993.
 * 9) Each player now gets to start a round, going from left to right for Rounds 1-3 and looping around for subsequent rounds.
 * 10) The flimsy "pointers" are replaced by a set of much sturdier ones that are far more effective at stopping the Wheel.
 * 11) The Speed-Up round is introduced, signified by a four-chime bell (previously used as the end-of-round signal on Jeopardy!) in Rounds 3+ to denote the final round of the game. Chuck gives the Wheel a "Final Spin", and the amount that he lands on is the value of each consonant during Speed-Up. The player in control when the Final Spin chimes sound gives a letter; if the letter is in the puzzle, s/he has five seconds to solve the puzzle once Susan turns them over and moves out of the way. If a wrong letter is called or the time limit expires, play passes to the next player. Further, contestants may not call vowels for the first 30 seconds of Speed-Up, and likely lose their turn if they do; a series of beeps, possibly the "only vowels remain" ones, sound when this time limit expires, although vowels do not award or cost any money.
 * 12) Speed-Up rounds use a split-screen shot, with the upper half displaying the puzzle board and the lower half showing the players and their main displays (plus the "ON ACCOUNT" displays, if applicable). The only sounds used during the Speed-Up are the buzzer (when the five-second time limit expires) and the "only vowels remain" beeps.
 * 13) A sponsor list is added. If its appearance on June 7, 1976 is any indication, it is prefaced by "THE FOLLOWING HAVE PAID AND/OR FURNISHED PRIZES TO NBC FOR PROMOTING THEIR PRODUCTS", centered, above the spinning Wheel.
 * On January 6: Vlcsnap-00006.png
 * Bankrupt is hit at least once, a fact the weekly Variety notes in an article on the 15th.
 * Contestant June wins at least $3,800, buying a $3,200 mink coat which she wears for the rest of the show. Following Round 3 (or possibly 4), she tells Chuck that "You're the first man who ever gave me a mink coat.", walking over to his area and giving him a kiss on the cheek.
 * For the first known time, a puzzle is discarded, likely Round 3. During the credits, Charlie mentions either the puzzle solution or the fact it was discarded, followed by an announcement that June (pronounced "joo-knee") was credited with her winnings, a new puzzle substituted, and the tape edited. This was most likely due to Susan turning a wrong letter, something she was known to have done frequently in the earliest days.
 * The January 6 show is known to exist, as clips of it were used in the show's E! True Hollywood Story. Clips were also used in promos that aired the week of December 30, 1974.
 * On January 6 or shortly thereafter, Giorgio begins providing Susan's wardrobe.
 * As of January 6:
 * The opening is approximately the same as it was on the 1974 pilots.
 * The main contestant displays are still white.
 * There is still a ring of lights above the Wheel, and at least some overhead shots continue to use it.
 * The center of the Wheel still changes color with each spin.
 * Puzzles are still introduced with an angled shot that includes the host and Wheel.
 * After the January 8 show is taped, Goldstein tells Chuck that he has never seen a game show host make a mistake and draw everyone's attention to it. Chuck responds by saying that everyone makes mistakes, so they should leave it in rather than edit it out.
 * Initially, there is no rule stating that puzzles must be solved exactly as they appear on the board, which was likely also the case on the pilots. The rule was apparently added the day after a contestant is ruled correct despite transposing the first and third words of TWEEDLEDUM AND TWEEDLEDEE (although they are generally referred to in the "dee"-"dum" order).

February 1975 :
 * An NBC press photo dated February 5 shows Chuck and Susan at the Rounds 3+ Wheel used on the premiere, with the doors behind them. Whether the date indicates that these elements were still in place at this point is unknown, as various publicity shots have been recycled and "re-dated" over the years.

March 1975 :
 * For the week of March 10, Wheel and NBC's other daytime games (Blank Check, Celebrity Sweepstakes, High Rollers, The Hollywood Squares, and Jackpot!) participate in the Shamrock Sweepstakes.
 * On March 17, the biggest winner of each show from the previous week appears on Celebrity Sweepstakes, as do Chuck and NBC's other hosts (Art James, Jim McKrell, Alex Trebek, Peter Marshall, and Geoff Edwards).
 * The show begins with all twelve onstage, most likely in the six spots normally occupied by the celebrity panel; Sweepstakes regular Carol Wayne (according to the Lebanon Daily News on March 15, Bob Hope) draws a name out of a drum, at which point the other players and their hosts are put in an isolation booth. The remaining host reads a five-part question about Irish-American people (written by Bolen and Jack Samuels, head of NBC's Compliance & Practices office), to which the player must give all five answers to win $100,000. An incorrect answer means that a new name is drawn and the same question is asked by that host, continuing as necessary until a correct answer is given (including, if needed, carrying over to the next show {although this is not needed}).
 * A copy of this episode exists on audio tape, held by Jimmy Owen.
 * Info on the Sweepstakes, including the multi-part question and its answers, appears in Maxene Fabe's 1979 book TV Game Shows!

April 1975 :

May 1975 :

June 1975 :
 * Likely by the end of this month (according to one recollection), and definitely by November 3, the prop at center stage is removed at Merv's insistence. If the photos shown on the Milton Bradley games (see "October 1975") are any indication, the prize platforms are temporarily put behind the puzzle board, as was the case in the 1974 pilots.
 * Assuming the above was the case, a golden curtain that also stretches between the puzzle board and Wheel debuts after at least one week. The curtain, decorated vertically with lights, lowers after Chuck's entrance and raises after each round to reveal the shopping prizes.
 * Also assuming the above was the case, the set photos used in the Milton Bradley games are taken during this "interim" period and confirm several aspects about the show (all of which are definitely in place by October 31):
 * The Round 1 Wheel layout has changed by now, with the minimum now $100: the tan $75 becomes a second $500, the sole $25 becomes $300 (if it did not increase before the other spaces; see below), the red $50 becomes $150, the yellow $75 becomes $200, and the blue $50 becomes $100. Based on available info about Round 3, the top value is still $1,000 and the sole $50 becomes $150. Also, the tan $200 near $175 becomes pale orange.
 * The pricetags used in shopping rounds change to shorter black characters on a blue background, encased in white holders.
 * The main contestant displays become the same color as the arrows (red, yellow, and blue from left to right).
 * The thin-flap "pointers" are still in use.
 * The special spaces still have their original appearance.
 * Available footage of a 1975 Belgian episode shows a Round 1 Wheel using the January 6 layout with slightly different wedge placement and the values multiplied by 10, albeit with no 250 spaces. If this is a reflection of the American version, the sole $25 increases to $300 (and the minimum value becomes $50) before the other two-digit values are removed.
 * Probably at this point, and definitely by June 7, 1976, the light ring above the players is removed and the Wheel's center no longer changes color.

July 1975 :
 * A "Fun in the Morning" promo airs between about July 4 and September 26, consisting of publicity shots from Celebrity Sweepstakes, Wheel, High Rollers, The Hollywood Squares, The Magnificent Marble Machine, and Jackpot! Strangely, the Wheel pictures are one each from the Shopper's Bazaar pilot and the first Byrnes pilot.
 * The July 15 show is held on audio tape by Archival Television Audio, Inc.

August 1975 :
 * The August 29 show is held on audio tape by Archival Television Audio, Inc.

September 1975 :
 * Lin Bolen leaves NBC sometime between the beginning of this month and March 31, 1976 (a Variety article from the latter states that she was present when the Fall season began, but CBS overtook NBC by the time she left). On Wheel, this results in contestants generally playing puzzles at their own pace rather than very frequently following her insistence on playing to the last consonant to maximize winnings.
 * As of September 12, Wheel holds 2nd place among all daytime network games, trailing only Celebrity Sweepstakes. At this point, it draws a 31 share on the Nielsen ratings system.

October 1975 :
 * By the end of this month, Milton Bradley releases two board game adaptations; they are the only ones to be released in the 1970s, and the only ones to use the shopping element. As mentioned under "June 1975", the pictures used on the box and instruction booklet show a set that does not use the doors or curtain; rather, the prizes are behind the puzzle board, which would indicate an "interim" period.
 * These games confirm several gameplay aspects about the show at the time of their release, including:
 * 1) The categories in use at this point: Event, Fictional Character, Landmark, Person, Phrase, Place, Thing, and Title. An old version of the show's website stated that Wheel began with six categories, while one recollection says that Phrase did not exist in the earliest months. It is likely that the puzzles were still only Person-Place-Thing when the show debuted, with Fictional Character-Landmark-Event being extensions; if so, Phrase and Title are the two "additional" categories.
 * 2) During shopping rounds, contestants may now place any part of their winnings on a gift certificate in addition to the existing "on account" option; players may also place some money "on account" and some on a gift certificate. However, from this point until the removal of the shopping rounds, most contestants opt for the gift certificate. (Presumably, Charlie's closing spiel is amended at this point to add "Gift certificates do not include sales tax.")
 * 3) Punctuation is still ignored (i.e., FISHERMANS WHARF instead of FISHERMAN'S WHARF).
 * 4) There is still no rule stating that puzzles must be solved exactly as they appear on the board (although given the absence of the "only vowels remain" rule, this may be an oversight by Milton Bradley).
 * 5) Buy A Vowel is still present, although contestants can no longer buy vowels at their discretion and must land on it to do so. As before, players who land on the wedge with less than $250 lose their turn. In addition, money put "on account" can be spent on vowels, and it would appear that it takes precedence over the colored displays if the wedge is hit (a rule which was likely in place from the beginning, but this is uncertain).
 * 6) Players are now able to call vowels during the first 30 seconds of Speed-Up rounds.
 * Sometime between the release of the First Edition and that of the Second, at least Thing and Person begin using their respective "plural" forms (Things and People, respectively).

November 1975 :
 * November 3 is NBC's Daytime Gigantic Game Gala, a week-long celebration involving Wheel, Celebrity Sweepstakes, The Hollywood Squares, and The Magnificent Marble Machine.
 * For this week, Wheel airs for a full hour from 10:30-11:30 AM, resulting in the only known week with three hour-long daytime network games (the others being Squares {celebrating the start of its 10th year} and The Price Is Right {permanent expansion}). Neither High Rollers nor 3 for the Money air this week.
 * The budget is almost certainly increased for this week: the available footage (see below) shows a 1976 Cadillac Eldorado coupe on-set and the Round 3 layout used for at least Round 1, with $1,000 as top value and the (dark orange) Free Spin wedge in place of the Bankrupt near Lose A Turn.
 * The November 3 show is known to exist, as a 20-second clip of the opening was shown on the March 21, 2000 episode of The Roseanne Show (rerun July 5), on which Chuck was a guest.
 * By November 3: OpeningLogo11-3-75.png
 * The opening is slightly altered to remove the chroma-key shots of the prizes, while Chuck now enters from the contestants' right and walks up to his part of the railing. It otherwise appears to be the same as it was on the 1974 pilots.
 * Buy A Vowel and the second Lose A Turn are retired. The Round 1 layout replaces Buy A Vowel with a red $400.
 * The sole $175 in Rounds 2+ is increased to $200, which probably only lasts for this week.
 * Bankrupt, Lose A Turn, and Free Spin adopt their normal appearances. It is possible that this change took place before Buy A Vowel was removed, but this is uncertain.
 * The "pointers" are changed to white, teardrop-shaped "flippers".
 * The curtain has definitely replaced the doors.
 * It is likely that the aforementioned Wheel layout alterations are removed on November 10, most likely barring Buy A Vowel and the second Lose A Turn.
 * Wheel does not air on November 27 due to the Macy's Thanksgiving Day Parade.

December 1975 :
 * On December 1, Wheel again expands to 11:30; as a result, High Rollers moves to Noon and The Magnificent Marble Machine to 12:30. Changes made for the hour-long format, most of which were likely also used on November 3-7, are believed to include the following:
 * Three contestants (including the returning champion, if applicable) play a three-round game during the first half-hour with $500, $1,000, and $1,500 as the top values. Immediately afterward, a second set of contestants play a three-round game much like the first.
 * The winner of each game plays a one-round "Head-To-Head All-Cash Showdown" with $2,000 as top value and the puzzle chosen in front of the puzzle board (reading WHEEL OF FORTUNE) from one of three bowls marked by category. Further, one wedge is placed on the Wheel which corresponds to a prize; if a contestant hits Bankrupt while holding the Prize wedge, it is placed back on the Wheel.
 * The winner of this round plays a Bonus Round with the same rules as the Star Bonus Round, described in further detail under "March 1978".
 * On December 31 (taped in November), contestant Rob Mandel wins $21,000.

1976
January 1976 :
 * Wheel does not air on January 1 due to the Tournament of Roses parade.
 * On January 19, Wheel returns to a half-hour, now at 11:00 AM; High Rollers moves to 10:30, while The Magnificent Marble Machine (which had been on a two-week hiatus) returns to the schedule at Noon in an all-celebrity format. Most elements added for the hour-long format are retired, some temporarily.
 * Likely on January 19, the show holds "NBC's All-Star Dream Machine Championship", a week-long tournament of champions with the nine biggest winners up to that point (five from the hour-long format, the others from before then). Three players compete on Monday-Wednesday, with the winners then playing a two-day "grand championship" (a prototype of the Friday Finals, and the first known use of such a format).
 * The Wheel layouts use $500, $1,000, and $1,500 as the top values, suggesting that they were held over from the hour-long shows.
 * On at least the Monday show, the opening begins with the logo on an overhead shot of the Wheel, which becomes the norm in 1983.
 * On at least the Monday show, all nine players are shown as Chuck mentions their totals. These include Rob Mandel ($21,000 "in November"; see above) and Judy Bongarzone. It is possible that, like "Some of the Greats!" in February 1995, clips or photos of their original appearance(s) were shown during the week.
 * The Monday show, held by the Paley Center for Media, is Richard/Patty/Rick.
 * According to Maxene Fabe's 1979 book TV Game Shows! and the 1987 book Wheel of Fortune by David R. Sams and Robert L. Shook, Judy wins the tournament and $64,461, including a Mercedes.

February 1976 :
 * Sometime this year, an episode airs in which contestant Rob Burns purchases a trip to Bermuda which becomes his honeymoon destination. His daughter, Cheron, appears as a contestant on December 8, 2009 and relates the aforementioned.

March 1976 :

April 1976 :
 * On April 29, Nancy becomes the sole producer, slightly over two weeks after Rhinehart announces his departure from the show (he is promoted to being the network's West Coast Daytime Program Development Director in May). Presumably, the full credit roll is altered to start with her credit once the tapings catch up.

May 1976 :
 * The May 20 show (Elliot/Kathi/Lee) is held by the Paley Center for Media.

June 1976 :
 * On June 2, 3, or 4, contestant Linda sets a single-round winnings record of $8,325 and a single-day half-hour winnings record of either this amount or slightly more.
 * By June 7 (#368; Gerry/Linda/Lee):
 * The opening is replaced by a new one that shows a wide shot of the set and closeups of several prizes. Charlie's intro is changed to "Just look at this studio, filled with beautiful and imaginative gifts, which can be purchased today on Wheel of Fortune! Total retail value of all these prizes: more than [amount]! Now, let's meet the host of Wheel of Fortune: Chuck Woolery!"
 * The "tall, thin" font for the money graphic has been replaced by a thicker font, similar to Impact, which remains for the rest of the daytime run.
 * Susan now enters from Chuck's left when he introduces her. At this point, she is still using an ECM-51 microphone.
 * The contestant score displays become white again, but continue to show just four digits and a dollar sign.Round1-76.jpg
 * Each puzzle is now revealed by a head-on shot of the blank spaces. On at least the 1974 pilots and 1975 premiere, an angled shot was used which also showed the Wheel and host.
 * The pricetags used in shopping rounds are changed to black (or greenish) characters on a white background with an elegant design surrounding the price, a style which remains for the rest of the shopping era.
 * The Wheel is altered a bit:
 * Many spaces on the Wheel become gold: the tan Free Spin, $450, and $250 plus the yellow $200 near $275 in Round 1; and the tan $600 and $100 in Round 2.
 * The pale-orange $200 in Rounds 2+ is decreased back to $175.
 * The orange $500 in Round 2 becomes red, swapping places with the Bankrupt three spaces clockwise, and the tan $200 in Rounds 2+ increases to a yellow $400.
 * As of June 7:
 * The original curtain is still in use.
 * There is still no sound effect for hitting Bankrupt.
 * Champions may still return for up to five days.
 * The original category cards are still in use.
 * The puzzle board's light border still turns on for correct letter calls.
 * The chroma-key closing shot is still in use.
 * The Merv Griffin Productions logo still looks about the same as it did in September 1973.
 * On June 7: Killtheumpire.jpgHugger.jpg
 * Perhaps coincidentally, the category cards are brown, matching Susan's outfit.
 * During Round 1, the buzzer sounds on a correct letter, followed by a ding immediately after.
 * In Round 1, Gerry mis-solves KILL THE UMPIRE as KILL THE VAMPIRE with the I's and U missing. Linda then gives the correct answer for $925, after which Chuck says "You've made a lot of money off other people's mistakes."
 * After Charlie describes the Round 1 shopping prizes, Chuck mentions getting letters from people who don't like seeing him hug contestants. He responds with "I like to hug folks. I'm a hugger. A lot of people are handshakers; I'm a hugger. And one more thing: if you were here, I'd hug ya too!"
 * During Round 2, Lee loses a then-very high $2,750 to Bankrupt.
 * After Lee solves the Round 3 puzzle (NORMAN ROCKWELL) for $800, Chuck has her spin one more time before announcing the winner. She hits $1,500.
 * Following this spin, Chuck asks an offstage staff member (possibly Nancy) about returning champion Linda's scores. Mention is made of her single-round record the previous week, and that she currently is second in half-hour total winnings with $23,200. (It is not known what the record was considered to be, although it may have been the aforementioned $64,461 won by Bongarzone.)
 * The sponsor list begins with "THE FOLLOWING HAVE PAID AND/OR FURNISHED PRIZES TO NBC FOR PROMOTING THEIR PRODUCTS", centered, above the spinning Wheel. (This may have been the original version, but this is uncertain. The available copy of this episode also shows what may be a colon at the end.)
 * Later in the credits, the curtain raises up to allow Chuck, Susan, and Linda to go to the boat she purchased.
 * June 7 is the earliest Wheel episode, one of only three daytime episodes, and the only episode hosted by Chuck to be aired by GSN; the network reran it in 2007 as part of a special marathon following Merv's death. Per the network's standard at the time, any mid-show plugs were cut out and the credit crunch began right after Chuck and Susan signed off (resulting in the show abruptly ending during the sponsor list, despite having a full credit roll).

July 1976 :

August 1976 :

September 1976 :

October 1976 :

November 1976 :
 * Wheel does not air on November 25 due to the Macy's Thanksgiving Day Parade.

December 1976 :

1977
(Note: This is the only year which does not have any footage known to circulate. As a result, the info listed here is mostly compiled from print articles and recollections.)

January 1977 :
 * January 24 is the first known Brides Week, with brides-to-be (grooms-to-be on the 26th) playing for prizes including a $5,000+ wardrobe, wedding cakes, rings, silver, crystal, fine china, and various home furnishings. It is also the first known instance of a themed week.
 * Summer Bartholomew makes her first known appearance this week, modeling specially-designed bridal gowns which are among the prizes.
 * A set of 20 color slides (photos) taken during this week's taping is known to exist. Some are from the 26th, while another appears to be a publicity shot of Chuck, Susan, and Summer; most of the pictures likely represent the week as-aired. In May 2012, the slides were put up for auction on eBay with a starting price of $12.79 (including shipping) and photos of 12 slides available for viewing; the auction closed with no bids.
 * By January 24, the curtain's lights are removed.
 * As of January 28, the contestant score displays and arrows still look the same as they did on June 7, 1976.

February 1977 :
 * On an episode around this point (known to be between January and March), contestant Beverly mis-solves the puzzle TED KNIGHT as TED NUGENT, likely with only the T's and D showing. While this episode is known to exist, it was stolen (along with Beverly's U-Haul truck) on May 25, 1981 while she was staying at a Motel 6 in Tulsa, Oklahoma; its location is currently unknown.

March 1977 :
 * On March 16, Merv takes out a single-page print ad noting that Wheel attained the highest audience share of all daytime network programming for the weeks of February 14 and 21.

April 1977 :
 * Sometime this year, an episode airs in which a female contestant purchases a trip; the trip results in her getting married and having a daughter. The daughter, Sarah, appears as a contestant during the College Week of May 12, 2003 and relates the aforementioned.

May 1977 :
 * On another episode sometime this year, contestant Gaylee Gillmore purchases a few prizes. Her son, Paul Hermosillo (whom Gaylee was pregnant with during her appearance), appears as a contestant on November 27, 2008 and relates the aforementioned. This Wiki has narrowed Paul's birthday to between September 19 and October 27, 1977.

June 1977 :
 * As of June 15, Wheel is still the highest-rated daytime series on at least NBC.

July 1977 :

August 1977 :

September 1977 :
 * At about this point (no later than September 7), Susan is absent for at least four weeks due to an accident while rehearsing for the second Circus of the Stars, which airs December 5. Summer Bartholomew returns to fill in for her.
 * Susan Morrison, a married model living in San Diego, plays on September 13 and 14; among the prizes she wins is a trip to Hawaii.
 * Arte Johnson fills in for Susan on at least one episode in September, most likely the 30th. It is known that he appears to plug his show Knockout, which debuts October 3.

October 1977 :

November 1977 :
 * Wheel does not air on November 24 due to the Macy's Thanksgiving Day Parade.

December 1977 :
 * Possibly by the end of this year, and definitely by April 6, 1978, a slide whistle sound is added for landing on Bankrupt. According to one recollection, its first use results in Chuck saying "What was that?" and laughing.
 * Most likely on the same day, and definitely by March 27, 1979, the slide whistle begins to be used if Chuck hits Bankrupt on the Final Spin, essentially a running gag that remains until about mid-1985 or so.

1978
January 1978 :
 * Wheel does not air on January 2 due to the Tournament of Roses parade.
 * The January 18 show (#785) is held by the Paley Center for Media. The first nine seconds were used on the ceremonial 3,000th and 4,000th nighttime shows, the latter dating it to 1983.
 * By January 18, Charlie's opening spiel is slightly extended to mention three prizes as the camera shows close-ups of them: "Just look at this studio, filled with trips...jewelry...a station wagon...which can be purchased today on Wheel of Fortune!" (The rest is presumably the same as on June 7, 1976, but this is uncertain.)
 * By January 18, the contestant score displays are extended to show five digits and a dollar sign.
 * Sometime this year, contestant Robbie Goldstein (or Goldstein Diamond) plays on at least two episodes. Her daughter, Erin, appears as a contestant on April 21, 2011 and relates the aforementioned.

February 1978 :
 * February 6 is Brides Week, presumably played like the 1977 one. Roselon Industries (specifically including R. R. Adams {company president} and Tom Dove {Vice President of Merchandising}) commends the show's staff "on the excellence of their fashion presentation" in a Variety advert on the 2nd.
 * As of February 10, Jeff Goldstein is still director. Sometime afterward, possibly by April 6, he is replaced by Dick Carson.

March 1978 :
 * By March 15 (Carol/Beth/Maryann):
 * The end of Charlie's intro reverts to "And now, here's your host: Chuck Woolery!"
 * The Wheel layouts change a bit:
 * Round 1: The blue $100 near Free Spin becomes $400, the blue $100 next to Lose A Turn becomes $400, the orange $100 near Bankrupt becomes $500, and the blue $100 next to Bankrupt becomes $350.
 * Round 2: The sole $175 is again increased to $200, which carries over into subsequent rounds.
 * Rounds 3+: The blue $200 next to Lose A Turn becomes a dark-blue $400, while the red $200 between the Bankrupts increases to $350.
 * The contestant arrows are redesigned: they are now brighter and come to a point, with the flipper in the center of the point.
 * The category cards are changed to a thin, monospaced font display in various colors, usually matching Susan's outfit barring neutral colors or multicolored outfits. Unlike the prior style, which was only shown sporadically due to being on art cards, the new displays are present on all shots of the puzzle board.
 * The puzzle board's border now stays lit for the entire game, instead of lighting up only on letter reveals.
 * On March 15:
 * The category displays are red, matching Susan's outfit.
 * For the first known time outside of the Second Edition game, a "plural" category is used: in this case, Things.
 * Following Round 2, Chuck notes that the show has given away a total of three or four "ceramic dogs" (not specified, but known to be Dalmatians) and asks the staff whether one of the dogs had puppies.
 * One round is the first known appearance of Quotation: HERE COMES PETER COTTONTAIL.
 * Gordon MacRae makes an appearance after the game.
 * On an episode after the above changes, but before the Star Bonus debuts (Barbara/Herb/Pat):
 * The category displays are purple, matching Susan's outfit.
 * Lose A Turn has a white stripe down the left side and a thick black line down the right, an odd appearance which seems to also be present on April 7.
 * Pat puts $15 "on account" after Round 1.
 * During Round 3, Chuck mistakes the Final Spin chimes for the "only vowels remain" beeps, and is corrected from offstage.
 * Barbara purchases a 1978 Camaro for $6,125 after Round 3.
 * By the above episode, the category display begins to be present during Speed-Up rounds, albeit in white rather than the color of Susan's outfit. This practice was likely in place when the displays debuted.
 * By the above episode, the show's logo returns to the end of the opening.
 * The Star Bonus token is introduced sometime between March 16 and April 6, placed on the orange $100 next to Free Spin during Round 1, the tan $100 in Round 2, and $150 in Round 3. The token cannot be lost to Bankrupt nor forfeited by failing to solve the round's puzzle, but is removed from the Wheel following Round 3 to play a fourth round. There are three known Star Bonus Rounds; one is mentioned below. StarBonus4778.jpg

April 1978 :
 * On April 5, contestant Karen retires with over $16,000.
 * Veteran game show contestant Scott Hostetler plays on April 6 and 7.
 * By April 6 (Scott/Glenda/Gail):
 * Susan begins entering through the center of the curtain, a tradition that with rare exception continues for the rest of the shopping era.
 * The blue $400 near Free Spin becomes red, presumably because it sat next to a blue $300.
 * The chroma-key shot of the Wheel at the end of the show is removed.
 * Nyesta and Augustus begin providing the wardrobe for Susan and Chuck, respectively.
 * On April 6, the first commercial outro is a closeup of the Star Bonus token, zooming out to a full shot of the Wheel.
 * On April 7 (Scott/Peggy/Laura): LoveyDovey.jpg
 * Various shots of Chuck in front of the curtain appear to have been added in post-production due to the Star Bonus, particularly the commercial outro and intro during Round 2.
 * The Round 1 puzzle LOVEY-DOVEY is both the first known instance of punctuation and one of the few known puzzles not to contain any of the five most common consonants (T, N, S, H, R).
 * During Round 1, the buzzer does not sound after Peggy calls S, and a ding sounds after she calls M. Later, the buzzer sounds just as Scott starts to spin.
 * During the Speed-Up round, the audience applauds for the first correct letter. Shortly afterward, the buzzer accidentally sounds twice. A turn later, the buzzer does not sound to signal the end of Laura's turn.
 * After the final shopping segment, Chuck mistakenly offers the "on account" option.
 * Peggy sweeps the game. Afterward, as Chuck mentions that Scott has the Star Bonus, the camera zooms out too far and to the right.
 * The Star Bonus Round is played, which results in the contestant interviews being edited down considerably. The prizes are a trip to Las Vegas (Easy; $675), a sterling-silver tea set (Medium; $2,303), a diamond pendant (Hard; $4,060), and a Porsche 924 (Difficult; $13,586). Scott plays for the car, but fails to solve PABLO PICASSO.
 * Charlie's closing spiel about the prizes (see below) is overlaid by a different voice saying "Additional prizes furnished by Jockey Club Resort, Bob Smith Porsche Audi." Charlie is still audible underneath, although his voice appears to stop before saying "Gift certificates do not include sales tax.", so it is not certain whether the line was actually present at this point.
 * The eligibility disclaimer reads "CONTESTANTS WERE FURNISHED WITH COMPLETE RULES, MUST MEET ELIGIBILITY REQUIREMENTS AND WIN ONLY ANNOUNCED PRIZES". This may have been the style from the premiere, but this is uncertain.
 * By April 7:
 * Some contestant nametags begin using a thicker font and have varying lengths based on the length of each player's name. The old fixed-length nametags continue to appear on an increasingly sporadic basis through the end of the shopping era.
 * Charlie's closing spiel about the prizes is changed to "The prices of the prizes were furnished to the contestants prior to the show and have been rounded off to the nearest dollar." On January 6, 1975, this was simply "The prices of some of the prizes were furnished to the contestants prior to the show."
 * The beginning of the sponsor list is slightly altered: "PAID" moves up to the first line, "FURNISHED PRIZES" to the second, "NBC FOR PROMOTING" to the third, and "THEIR PRODUCTS" to the fourth. A colon is also present at the end, although it is uncertain whether it was also present on the prior version of this graphic.
 * As of April 7, the 7's on the Wheel still have a round bottom, and $900 is still next to Bankrupt in Rounds 2+.
 * On April 24, the show moves to 11:30 AM.

May 1978 :
 * According to personal recollections, at least two more Star Bonus Rounds are played during the token's life: another Difficult (KNOCK ON WOOD) and a Medium (TOSSED GREEN SALAD).

June 1978 :
 * The Star Bonus may still be in use at this point, as a Match Game episode taped in May or June (specifically, the June 26 debut of the Star Wheel) contains a reference to it.

July 1978 :

August 1978 :
 * At the end of this month, as mentioned in the October 16 issue of Broadcasting (Page 38), Wheel holds 15th place among all daytime network shows, tied with the second half of The Price Is Right. At this point, it draws a 6.1 on the Nielsen ratings system with a 27 share; among the then-coveted demographic of women 18-49, it is in 22nd place with a 1.15.

September 1978 :

October 1978 :

November 1978 :
 * Wheel does not air on November 23 due to the Macy's Thanksgiving Day Parade.

December 1978 :
 * On December 25, Chuck's wife (Jo Ann Pflug) and daughter (Melissa) make an appearance, as does Charlie in a Santa Claus costume. The photo at right, showing Chuck, Jo Ann, Melissa, Susan, and Charlie in front of the puzzle board (reading HAPPY HOLIDAYS), is the only known remnant of this episode.

1979
January 1979 :
 * Wheel does not air on January 1 due to the Tournament of Roses parade.

February 1979 :

March 1979 :
 * By March 2 (Angela/Leo/Juanita):
 * The opening is changed to "Look at these luxurious prizes! Fabulous merchandise, just waiting to be won today on Wheel of Fortune! [three prizes are described] Total retail value: over [amount]! And now, here's your host: Chuck Woolery!"
 * The money graphic is moved back to the end of the opening, and its dollar sign is centered next to the numbers.
 * The Star Bonus is retired, an event which very likely happened much earlier.
 * The 7's on the Wheel are slightly altered to have a flat bottom.
 * A rule is added requiring players to solve the puzzle exactly as it is shown on the board. (Although it was very likely added much earlier, this is the first known instance of Chuck pointing out the rule; he does not do so on June 7, 1976 and April 7, 1978.)
 * The Bankrupt next to $900 in Rounds 2+ is swapped with the $200 wedge three spaces counterclockwise. This was likely done to even out the Wheel, as the two Bankrupts had been separated by just five cash wedges in Round 2 and eight in Rounds 3+.
 * On March 2:
 * The category displays are red, matching Susan's outfit.
 * For the only confirmed time during this era, the puzzle board's chase light sequence is reversed, going counterclockwise.
 * A buzzer fails to sound on an incorrect letter in Round 2.
 * On March 27 (Gwen/Brian/Anita):
 * The audience can be heard muttering for a few seconds in the opening before "Big Wheels" begins.
 * The first three spins of Round 2 are all Bankrupt, to which Chuck responds by beginning his Round 2 intro spiel again. It takes seven spins to reveal any letters in the puzzle FOURSCORE AND SEVEN YEARS AGO, and Bankrupt is hit a total of six times (which may be a one-round record).
 * In Round 2, Susan turns the V too hard, causing the plastic letter sheet to slide partway off the trilon.
 * Round 3 is the first known appearance of Occupation.
 * Chuck's Final Spin lands on Bankrupt.
 * By March 27, Roselon Industries begins providing Susan's wardrobe.

April 1979 :

May 1979 :
 * Summer returns on May 24 to fill in for Susan, who dislocated her shoulder in a car accident.
 * On May 31: Nickname53179.jpg
 * The category displays appear to be teal, matching Summer's outfit.
 * Nickname makes its first known appearance, in Round 1. It is not known if the category existed before this point (it is not present in Milton-Bradley's games), had a consistent presence between here and mid-1988, or if it was retired and brought back sometime.
 * Contestant Hilarie puts $5 and $89 "on account" after Rounds 2 and 3, respectively.
 * During Round 3, Summer forgets to turn an X and is reminded by Chuck.
 * During the credits, Summer's wardrobe credit (Roselon, same as Susan's) accidentally appears briefly before the sponsor list.
 * As of May 31, the curtain is still visible during the final segment and credits.
 * By May 31, the eligibility disclaimer is slightly altered: "WERE" becomes "ARE", while a comma is added after "REQUIREMENTS". The font is also thinner, possibly a result of turning off the "bold" setting on the computer used to create the monospaced displays.
 * By May 31, the Merv Griffin Productions graphic is altered to have "WHEEL OF FORTUNE Is Produced by" above it on two lines.
 * May 31 and June 1 may use the reversed chase light sequence, but this is uncertain due to the quality of the available footage.
 * Likely around this point, and into 1980, many games use a common theme to their puzzles.

June 1979 :
 * By June 1, the dollar sign on the money graphic returns to being above the first number.
 * By June 1, puzzles begin to use apostrophes.
 * On June 1, the category displays are blue, matching Summer's outfit.
 * As of June 1:
 * "Big Wheels" is still played when going to commercial.
 * The Wheel's top values are still $500/$1,000/$1,500, and $125, $275, $650, and $850 are still present.
 * Cynthia Washington, ex-wife of former San Francisco 49ers wide receiver Gene Washington, fills in for Susan the week of June 4.
 * Susan returns on June 11.

July 1979 :

August 1979 :

September 1979 :
 * Courtenay O'Connell plays on September 4 and 5 (taped August 14); on September 10, the St. Petersburg Times publishes an article about her experience.
 * On September 4, Courtenay purchases a blue $6,000+ Subaru BRAT following a single puzzle (known to be Phrase).

October 1979 :

November 1979 :
 * Wheel does not air on November 22 due to the Macy's Thanksgiving Day Parade.
 * A female contestant named Shauna plays on at least November 28 and 29, and is the basis of a documentary by Shauna Dillavou (born on the 28th and named after the aforementioned woman) called The Luckiest Shauna; Dillavou is known to have contacted Wheel looking for a copy of the November 28 show, but it does not seem to exist (she was not aware of returning champions until viewing the 1976 and 1978 episodes held by Paley Center).

December 1979 :
 * For this month, the puzzle board and contestant area are decorated for Christmas. Also, many Christmas-themed prizes are available for purchase.
 * As of December 4, Charlie's opening spiel is still the same as it was on March 2 and the money graphic still looks the same as it did on June 1.
 * By December 4 (Susan/Lea/Ginger), the Wheel is overhauled:
 * The colors are altered, most notably the use of only one shade of blue.
 * Top value in Rounds 1 and 3 are increased to $750 and $2,000, respectively.
 * The configurations are modified again:
 * Round 1: $750 replaces the $500 next to Bankrupt, the sole $125 is decreased to $100 and swaps positions with the brown $500, the sole $275 is decreased to $250, and the orange $500 is increased to $600.
 * Round 2: The sole $100 is increased to $150, the $600 by Lose A Turn is lowered to $400, the sole $350 is lowered to $200, and the sole $650 is decreased to $550. This is $550's first appearance since the 1974 pilots.
 * Rounds 3+: The sole $850 is reduced to $700, the sole $450 becomes $200, and $2,000 replaces $400 and swaps positions with the neighboring $350.
 * By December 4, a new music cue is introduced for all commercial breaks.
 * On December 4:
 * The category displays are light blue, matching Susan's outfit.
 * The first spin of Round 3 is likely done in post-production, as Chuck overreacts to Ginger's landing on $300.
 * During the Speed-Up portion of Round 3, the trilon containing the D in the puzzle RADIO CITY MUSIC HALL noticeably squeaks as Susan turns it. Also, the category display is present on the players' half of the screen, which itself is zoomed too far out.
 * At the beginning of the subsequent shopping round, an oak-framed bathroom mirror (part of a $302 oak bathroom-accessory set) shows a reflection of the puzzle board being wheeled away. Later, as Charlie describes it, the mirror shows a reflection of the Used Letter Board and an unknown staff member.
 * By December 13:
 * Charlie's closing spiel about the prizes is amended to end with "Gift certificates do not include sales tax.", which probably happened much earlier.
 * The curtain is no longer seen during the final segment and credits.
 * The eligibility disclaimer removes most of the space after each comma and adds a period to the end.
 * By December 31 (Lou/Allan/Jackie):
 * Charlie's intro is slightly altered to replace "luxurious" with "extravagant".
 * The dollar sign on the money graphic is moved down, lining up with the bottoms of the numbers. Strangely, it does not zoom in.
 * Holiday decorations are added to the curtain.
 * The returning-champion limit is decreased to three days, and total champion winnings of $10,000 or more are displayed without a dollar sign (on June 7, 1976, the display was left blank).
 * The prize manufacturer tags are now smaller; their font is changed to Peignot Bold.
 * The aforementioned commercial outro cue is replaced by an electric-guitar cue.
 * On December 31:
 * During Round 2, the puzzle-solve cue accidentally plays for a second instead of the "only vowels remain" beeps (itself played a second later). Once the puzzle is solved, the cue begins playing from the point it was cut off.
 * Rounds 1 and 2 are played entirely by the contestant who began them.
 * The December 4 commercial cue is used for the prize descriptions after Round 3.
 * In Round 4, the category chimes are played over a shot of Chuck.
 * Allan retires with $15,425, which Chuck mistakenly reads as $1,425 until being corrected from offstage.
 * For the first known time, the post-game chat is not done at or near the Wheel: Chuck and Susan sit at part of the Round 3 prize platform and promote their appearance during the Tournament of Roses pre-parade on January 1.
 * "Auld Lang Syne" plays from Chuck and Susan's sign-off through the end of the credits.
 * The eligibility disclaimer does not have its commas. As they are present on March 20, 1980, it is not certain whether this comma-less version was used for more than one episode.
 * As of December 31, the wedge next to $1,500 is still $200.

1980
January 1980 :
 * Wheel does not air on January 1 due to the Tournament of Roses parade.
 * On at least one show this year, Chuck wears a tuxedo. This may be from a Brides Week.

February 1980 :
 * At some point this year, adult film actor Ron Jeremy appears as a contestant (under his real name of Ron Hyatt) following the death of his mother. Among his winnings are a trip to Mazatlán.

March 1980 :
 * On March 19, contestant Becky puts money "on account". According to comments the next day, this works to her advantage.
 * On March 20 (Charlene/Becky/Les):
 * Charlene gets two Free Spins in a row during Round 1.
 * During Round 1, Chuck forgets on two separate occasions to ask if a contestant wants to use their Free Spin following an incorrect letter call.
 * Les' microphone falls off during Round 2. He quickly retrieves it, and it is reattached during the commercial break.
 * Becky puts $240 "on account" after Round 2, but loses it to Bankrupt on her only spin of Round 3.
 * During Round 3, the contestants are shown turning their backs during the mid-round commercial outro. As Chuck throws to break, a female voice (possibly one of the contestants) is heard saying "That means there's no time for a [uncertain word]". As Chuck does the Final Spin right after the show returns from commercial, the voice may have been referring to there being no time for a fourth round.
 * No music is played during the commercial outro after Round 3.
 * By March 20, the $200 next to $1,500 is increased to $800.
 * By March 20, the closing segment once again uses a shot of Chuck and Susan chroma-keyed into the center of the Wheel.
 * As of March 20:
 * Charlie's intro still uses "extravagant".
 * The electric-guitar cue is still used when going to commercial in all segments.
 * At least some shows still use themed puzzles (in this case: VINTAGE WINE, DRINK TO ME ONLY WITH THINE EYES, and SOBER AS A JUDGE).
 * On March 25 (Mazel/Bob/Kevin):
 * The category displays are blue, matching Susan's outfit.
 * During Round 3, Susan turns all four A's in the puzzle RAIN RAIN GO AWAY before they light up or their respective bells play.
 * A buzzer fails to sound on an incorrect letter in Round 4.
 * Following Round 4, the camera suddenly shifts to the right as Kevin selects his first prize.
 * Five rounds are played, the first known instance of such an event and an unusual one for the shopping era. Chuck refers to it as being the "first time in a long time", suggesting that it happened before.
 * Following the game, Chuck and Susan note that it is the last episode of unit manager Rob Keith, whom they say goodbye to. Oddly, Rob is not present on the full credit roll and the only person listed as unit manager is Michael Koljan.
 * Chuck and Susan's signoff is quite different than usual: "I'm Chuck Woolery," "And I'm Susan Stafford." "See you all tomorrow, bye-bye everybody." "Bye-bye, God bless!"
 * The ticket/contestant plug is done on a blue background between the fee plugs and sponsor list. While the practice of using such a plug was likely in place since the premiere week, it is not known how the plugs were presented prior to this episode.
 * Very strangely, the eligibility disclaimer misspells "FURNISHED" as "FURNISHD", and as a result "WITH" is one space further to the left than usual.
 * By March 25:
 * Charlie's intro reverts to using "luxurious".
 * The commercial outro cue used on December 4, 1979 returns for all breaks.
 * Full credit rolls begin with the show's logo and end with Merv Griffin's creator credit.
 * As of March 25, the money graphic still looks the same as it did on December 31, 1979.
 * As of March 25, there is still a $150 next to $600 in Rounds 2+ and a tan $150 between Bankrupt and Lose A Turn in Rounds 3+.

April 1980 :

May 1980 :
 * On May 6, a champion retires undefeated.
 * On May 7 (Paul/Diane/Cathy):
 * All three contestants are left-handed; one of them, Cathy, is from Paris.
 * During Round 1, Diane lands on Free Spin and, after receiving a token, tries to call an S. After her next spin, she is credited with the S, which is in the puzzle.
 * Early in Round 2, the trilon containing the P in STOP LOOK AND LISTEN is accidentally lit after T is called. The mistake is quickly corrected.
 * In Round 3, the contestants are shown turning their backs during the mid-round outro.
 * After the game, Chuck and Susan address rumors about the show's cancellation; while dispelling them, Susan notes that NBC's daytime schedule will be undergoing a few changes. Chuck replies with "In the meantime, we're gonna be doing this show until we get it right!"
 * By May 7:
 * The money graphic is again altered to center the dollar sign, as it was on March 2, 1979.
 * The show begins using both "new" commercial cues: the December 4, 1979 cue after each round, and the electric-guitar cue for mid-round breaks.
 * The $150 next to $600 in Rounds 2+ is increased to $250, as well as the tan $150 between Bankrupt and Lose A Turn in Rounds 3+.

June 1980 :
 * On June 9 (Fred/Lu/Heidi):
 * Heidi begins to call Z during Round 2, but stops herself and calls D instead. She is credited with the D, which is in the puzzle.
 * Chuck's Final Spin lands on Lose A Turn. His second attempt lands on $2,000.
 * By June 9, the December 4, 1979 cue is again used for mid-round breaks (in this case, during Round 3) and the electric-guitar cue is not used at all.
 * By June 20 (Ken/Linda/Charlotte), the money graphic returns to its style from March 25.
 * On June 20:
 * Chuck makes an odd comment to Susan after her entrance, saying she looks like "a little Swedish girl".
 * Charlie coughs briefly during the second prize plug, which Chuck brings up before Round 2.
 * Following Round 2, Charlotte reluctantly says "[I'll] take the...candy dish.", after which Chuck talks to her and the purchase is discarded. Following the prize plugs, Chuck remarks that the Marc Chagall print she bought is better than the other one the show had from him, that being "seventeen lizards sucking on an orange".
 * The slide whistle does not sound when Bankrupt is first hit in Round 3.
 * There is no inlaid contestant shot during the Round 3 shopping portion.
 * Chuck's Final Spin lands on Bankrupt.
 * After the game, Chuck and Susan discuss the waiting period for prize delivery (90 days). When asked by Chuck, an offstage staffer says they're shipped "whenever we get around to it".
 * By June 20, the commercial outro cues are changed up again: the electric-guitar cue is used after Rounds 1 and 4, plus the break during Round 3; the December 4, 1979 cue is used after Rounds 2 and 3.
 * Also on June 20, NBC airs a promo detailing the new schedule to begin the following Monday. The promo includes a Wheel clip of a female contestant right after solving CREPES SUZETTE (Things), and apparently screaming so loud that Chuck is seen with his hand up to his ear.

July 1980 :

August 1980 :
 * August 1 is taped as the series finale, due to a cancellation order from NBC boss Fred Silverman that is overturned by the time it airs. The episode features an appearance by Chuck's then-wife, Jo Ann Pflug. It is also Charlie's last regular episode until February 1989, as he leaves to announce The Toni Tennille Show.
 * On August 4, the show moves back to 11:00 AM.
 * Don Morrow fills in as announcer after Charlie's departure, likely announcing only the week of the 4th.
 * The August 4 episode opens with Chuck joking about the show's demise.
 * Jack Clark likely takes over as announcer on August 11.
 * On an episode probably from the week of August 4 or 11, Chuck urges viewers to call the number of the studio where Wheel tapes, giving it out on-air. The resulting 13,000+ calls cause blackouts in a few suburbs and a cutoff threat to be issued from the phone company; this results in the installation of a new, high-capacity phone line.
 * On August 22 (Carole/Mike/Nancy):
 * Mike is originally from South Africa, but living in Canada.
 * A bell fails to sound in Round 3 after the A's are purchased. Later in the same round, a buzzer sounds on a correct letter, and again over the puzzle-solve cue.
 * Chuck's Final Spin lands on Bankrupt.
 * The Wheel does not spin during the credits, and the camera shot is zoomed out farther than usual.
 * By August 22, the commercial outro cues are changed up once again: the December 4, 1979 cue is used when going to commercial during and after Round 3.
 * As of August 22, the beginning of the sponsor list still looks the same as it did on April 7, 1978.
 * Alex Trebek fills in for Chuck around this point, most likely the week of the 25th.

September 1980 :
 * At least September 15-18 feature NBC soap opera stars: Josh Taylor (Days of Our Lives) appears on the 15th, Ben Thomas (The Doctors) on the 16th, Barbara Rucker (Texas) on the 17th, and Douglass Watson (Another World) on the 18th. It was likely similar to Game Show Hosts Week, mentioned below.

October 1980 :
 * On October 8 (Sonny/Ruth/Janet):
 * The final round begins as a Speed-Up, which for the only known time during the Woolery era is played for a Giorgio gift certificate rather than shopping.
 * Chuck's Final Spin lands on Lose A Turn twice in a row.
 * Chuck and Susan do not sign off; rather, the final segment begins with the fee plugs.
 * By October 8, the beginning of the sponsor list is altered again: only the first letter of each word remains upper-case, and "NBC" is replaced by "The Production Company", resulting in "To" being moved to the second line and "Promoting" to the fourth. The colon is removed, and the first line is oddly left-justified (leaving a gap above "To").
 * Sometime this month (probably the week of October 20), an NBC promo airs detailing the new lineup following Letterman's departure. The promo includes brief clips of a Wheel episode probably from around this point.

November 1980 :
 * By around this point, the show generally stops using a common theme for all puzzles.
 * November 3-6 (and possibly October 31 as well) is Game Show Hosts Week, with NBC emcees playing for members of the audience, who also determine what prizes to buy in shopping rounds. The host competes against two contestants who play normally, and is otherwise a normal player (including participation in drawing numbers before taping to determine position). Wink Martindale and Jim Perry are among the participants, and it is rumored that Art Fleming also played.
 * According to one recollection, Perry plays on November 4 (taped October 18).
 * Bill Cullen plays on November 5, and based on comments the next day ("He blitzed everybody."), he sweeps the game.
 * On November 6, Tom Kennedy plays for Art against Monty and Minnie, winning $1,400. During the interviews, Chuck moves on to the next player (Monty) before being reminded about the audience member from offstage. A slightly echoed female voice is heard briefly during this, possibly Nancy Jones in her first known on-air appearance.
 * By November 6, the electric-guitar commercial cue is moved to the mid-show consolation prize plug (although it is barely audible on the 6th). The December 4, 1979 cue is now the only one used for commercial breaks.
 * By November 6, the ticket/contestant plug begins to be done over the spinning Wheel, which leads more seamlessly into the sponsor list. The font of the plug is also thinner.
 * As of November 6, Jack's intro still uses "luxurious".
 * November 7 begins the show's first Armed Forces "Week", plugged as such despite being stated on the previous show as beginning "tomorrow" (Friday).
 * Immediately following the Armed Forces episodes is Celebrity Week on the Town, possibly played like Game Show Hosts Week.
 * Minnie, the returning champion from November 6, probably returns on the 24th.
 * Wheel does not air on November 27 due to the Macy's Thanksgiving Day Parade.

December 1980 :
 * By December 18, and probably for the entire month, the set is decorated for Christmas in much the same way as 1979, albeit with a wreath on the curtain and thicker foliage behind the contestants.
 * By December 18, Jack's intro reverts to using "extravagant".
 * On December 18 (Laura/Joyce/Barbara):
 * Chuck's cord gets caught on the nearby car as he makes his entrance.
 * The contestant score displays are tinted yellow. They are normal on November 6 and December 24.
 * The shopping cue begins in the wrong place after Round 2, then starts again from the beginning.
 * After Round 3, the camera fails to switch to the first prize until Jack is halfway through describing it.
 * Joyce retires with $17,550.
 * As of December 18, the December 4, 1979 cue is still the only one used for commercial breaks.
 * By December 24, the commercial cues are changed up once again: for the first time in over a year, "Big Wheels" is used when going to commercial during Round 1 and after Round 3; the December 4, 1979 cue is used after Round 2, while the electric-guitar cue remains at the mid-show consolation prize plug.
 * On December 24 (Vicki/Bud/Linda):
 * The category displays are red, matching Susan's outfit.
 * Vicki's first spin runs into an error which is not explained clearly on-air, primarily since the error and resolution happen while the camera is focused on the puzzle board; the Wheel is reset, and she spins again.
 * During Vicki's first turn, for no apparent reason, an "8" appears on the display behind her.
 * There is a commercial break during Round 1, the first known instance of this happening.
 * Chuck mistakenly says that the top dollar amount in Round 2 is $2,000.
 * The Round 2 puzzle SLEIGHBELLS RING ARE YOU LIST'NIN' is the first known instance of multiple punctuation marks, and the largest known puzzle using the original puzzle board (all but nine trilons). It is solved by Linda for a then-massive $6,700.
 * After Linda buys a Mazda following Round 2, Susan is seen closing the driver's-side door from the inside. Once Jack gets to the car plug, Susan drives it around to stop in front of the prize displays, honks the horn, and gets out.
 * A buzzer fails to sound on an incorrect letter during Round 4.
 * Bud finishes in second place with a then-high $4,300, and Chuck notes that this would normally be a winning score.
 * No music is played during the commercial outro after Round 4.

1981
January 1981 :
 * Wheel does not air on January 1 due to the Tournament of Roses parade.
 * An Armed Forces Week is done sometime this year, most likely in a "sweeps" month and definitely by November 30. One representative each from the Army, Air Force, and Marines plays each day, with the cumulative winnings of each branch being split evenly among the five players. The set is almost certainly decorated for this week.
 * On the Friday episode of the above week (Mark {Marines}/Don {Army}/Jay {Air Force}):
 * "Into the Wild Blue Yonder" is played during the opening, fee plugs, and credits.
 * Jack's intro ends with "And now, here's your host and hostess: Chuck Woolery and Susan Stafford!" They are escorted onstage by the honor guard from the 22nd combat support group at March Air Force Base (now March Joint Air Reserve Base). This is the first known time that the hosts are introduced together, and the only known instance of such an intro in the Woolery era.
 * Oddly, Chuck does not appear to do the opening spin.
 * For the first known time, a full episode is played for cash (the hour-long shows played for cash in the Head-To-Head round). The prize platforms, which were used on Monday-Thursday and whose prizes were likely not split, are either not present or have the prizes replaced by Armed Forces logos and the like (and in the latter case, may be directly adjacent to support larger items such as banners).
 * A strange incident occurs in Round 2: the puzzle is initially revealed as Quotation, but about halfway through the round Chuck announces that it is actually a Title (THE MAN WITHOUT A COUNTRY). "Quotation" may have been present on the category display until the error was discovered, but this is uncertain.
 * All three contestants hit Bankrupt consecutively in Round 4.
 * The mid-show plug, for an Adam York gift certificate, is the only time Jack speaks during the game. He throws back to Chuck with "And now, the man with the money: Chuck Woolery!"
 * Five rounds are played, with a $750/$750/$1,000/$1,000/$2,000 structure and the second Bankrupt added in Round 3.
 * By the above episode, the electric-guitar cue returns to prominence: it is used after Rounds 2 and 4, during and after Round 5, and during the mid-show plug. It is not known what was used after Rounds 1 and 3, as the available copy of this episode (an audio recording) cuts directly from Rounds 1 to 2 and is missing the last portion of Round 3.
 * The Monday following Armed Forces Week begins "Celebrity Night on the Town", with various daytime stars. Chuck and Susan plug this on the above episode, stating that they will be going to Las Vegas; based on the below [City] Weeks, the Vegas trip likely consisted of location footage with the games played in Burbank.

February 1981 :

March 1981 :

April 1981 :
 * April 13 is the first known Teen Week, and the first known use of the regular Friday Finals format: three contestants compete on Monday-Thursday, and the three biggest winners return on Friday to play for savings bonds.
 * The April 15 show is Craig/Hilary/Marianna.
 * The April 16 show has Ian in the first position and Dina in the third, and Ian sweeps the game. Among his prizes is a small gold whistle from Tiffany Jewelers, which he receives in-studio and gives to Dina.
 * April 17 is Ian/Dan/Craig, with $2,000 added in Round 5. The rest of the gameplay structure may be the same as the aforementioned Armed Forces show, but this is uncertain.
 * By April 21 (Virginia/Jan/Lori), the electric-guitar cue returns to use for all commercial breaks and the mid-show car plug.
 * By April 21, the "house minimum" is $200. It was apparently $100 during the earliest episodes in 1975.
 * On April 21:
 * Jack's introduction of Chuck is "And now, let's meet your host: Chuck Woolery!"
 * Chuck mentions his habit of licking his finger before touching the Wheel, and that the producer (unnamed, but very likely Nancy Jones) replied by saying "You don't know where that Wheel's been!" His reply is simply that "I don't care where that Wheel's been!"
 * Virginia attempts to spin the Wheel during the Speed-Up round, but is stopped by Chuck before she can do so.
 * Later in the Speed-Up round, the buzzer fails to sound to end a turn.
 * A few turns later, Susan turns the N too hard, causing the plastic letter sheet to slide partway off the trilon.
 * Lori sweeps the game.
 * After the game, Chuck mentions that about two weeks ago, he had brought up the fact that the show has done over 1,600 episodes. Susan then hopes the audience's income taxes turned out well and wishes her mother and Scott Page a happy birthday before the two sign-off.
 * As of April 21, the Speed-Up round split-screen shot still looks the same as it did on April 6, 1978 (puzzle on top and players on the bottom, category display still present).
 * As of April 21, the beginning of the sponsor list still looks the same as it did on October 8, 1980.

May 1981 :
 * May 11 is San Francisco Week, with contestants from that city brought in to compete. This is the first known use of such a week.

June 1981 :
 * June 8 is Brides Week, known to have been promoted during the June 8 episode of Blockbusters.
 * June 22 is San Antonio Week, done the same way as San Francisco Week.
 * According to one recollection, the Game Show Hosts Week of November 1980 is rerun the week of June 29, one of the only known instances of daytime Wheel airing repeats, although it is not known how long this practice was done.
 * For these airings, the original fee plugs are replaced by a new set of sponsors, and a cutaway is done afterward to a list of these sponsors. According to a Teen Week contestant (see below), the players are sent new parting gifts by Wheel in the form of checks from the replacement sponsors, "who hoped we'd use the money to buy some of their product".

July 1981 :
 * If surrounding information is any indication, the week of July 6 also consists of repeats.
 * The Teen Week of April 13 is rerun the week of July 13.

August 1981 :

September 1981 :
 * September 21 is Portland Week, taped in August and done the same way as previous [City] Weeks. The week includes footage of Chuck and Susan at the Washington Park Rose Test Gardens, Portland's downtown mall, various fountains, the Columbia River Gorge, and the salmon fishing grounds near Astoria.
 * On an episode during Portland Week:
 * The category displays are purple, somewhat matching Susan's outfit.
 * Contestant Linda opts to solve the puzzle AIR TRAFFIC CONTROLLER before a voice (that of opponent Frank) tells her to spin again. She does so and hits Bankrupt, after which he solves for $1,800.
 * As of the above episode:
 * The curtain remains visible during all non-shopping portions of the show, except the credits.
 * The electric-guitar cue is still used for at least one commercial break (in this case, during Round 3).
 * $2,000 is still red, and the nearby $250 is still gold.

October 1981 :

November 1981 :
 * Wheel does not air on November 26 due to the Macy's Thanksgiving Day Parade.

December 1981 :
 * December 14 is Christmas Wish Week.
 * The opening for this week is "Look at these extravagant prizes! [three prizes are described] Total retail value: over [amount]! As we begin/continue Christmas Wish Week on Wheel of Fortune! And now, here's your host: Chuck Woolery!"
 * The five-and-a-vowel Bonus Round is in place by this point and referred to as the "Christmas Wish Bonus", suggesting that it was introduced this week. This may also have been a trial run exclusive to this week, as most sources indicate the five-and-a-vowel Bonus Round was introduced on the 28th.
 * On December 18 (Terry/Debbie/Vivia):
 * After Terry says he will be a "househusband" in January, Chuck says that "I'll be a househusband on December 26.", indicating that this week was taped after his decision to leave Wheel.
 * Vivia is referred to as "Smitty" on her nametag and throughout the show.
 * During Round 2, two vowel calls (O and E) and their reveals on the board are done in complete silence, with no applause at any point.
 * An instrumental version of "Frosty the Snowman" plays during the Round 3 prize descriptions.
 * For the first known time, a single category is used for three puzzles: Rounds 2 and 4 are Thing, while the Bonus Round is Things.
 * Following the Bonus Round, Susan mentions the set changes to take effect the following Monday.
 * By December 18, the commercial outro cues are changed up once again: "Big Wheels" returns, used after Rounds 1, 3, and the Bonus Round plus the mid-show catalog plug; the December 4, 1979 cue also returns, used after Round 2.
 * As of December 18, shopping rounds are still generally done if the final round begins as a Speed-Up.
 * The week of December 21 is Christmas in New York, done the same way as previous [City] Weeks.
 * The opening for this week is "Look at this glamorous set, filled with prizes! Fabulous and exciting merchandise including Christmas gifts, a diamond pin, bedroom furniture, a new car, home appliances! Over [amount] just waiting to be won today as we present Christmas in New York on Wheel of Fortune! And now, here's your host: Chuck Woolery!" The Wheel logo is not used, instead showing Susan walking in a light New York shower.
 * The curtain does not come down after Chuck's entrance on at least the 25th; rather, Susan walks out from next to the puzzle board as the turntable spins.
 * On at least the 25th, "HOTEL ACCOMODATIONS AND INTERVIEW FACILITIES FURNISHED BY HOTEL PARKER MERIDIEN NEW YORK" appears between the fee plugs and sponsor list, using the monospaced font on five lines over the spinning Wheel; on at least this occasion, "ACCOMMODATIONS" and "MERIDIAN" are misspelled.
 * On December 21: Wheel_of_Fortune_1982_Puzzleboard.pngWideSetShot122581.png
 * The set is overhauled. From left to right:
 * The puzzle board adds an extra row and another nine trilons, for a total of 48 (11 on the top and bottom rows, 13 in the middle two). It also has a larger, ribbed, golden frame shaped like a sideways 3 whose chase lights move counterclockwise on the left side and clockwise on the right. The trilon designs and letter font are unchanged.
 * The three prize platforms are replaced by a single, large, three-sided turntable with two spiral-esque pillars flanking it and light-up white trees (which become green and brown depending on the time of year) to the sides of those. The turntable spins during the opening and credits, and rotates to each prize showcase depending on the round.
 * The Wheel's base is changed to a more golden look, with four layers: the top has small bulbs; the layer below it has flashing lights seen in overhead Wheel shots; the third has larger bulbs that flash six at a time when the spinning Wheel is seen from the base's perspective (three at a time for the other layers); and the bottom has sword blade-like spikes and bulbs similar to the third layer. The first three layers' lights continue to flash counterclockwise, while the bottom layer's lights continue to flash clockwise.
 * Brown arches are added under the railing, both in front of Chuck and between the displays, while the poles under Chuck's portion are painted brown.
 * The green glitter is removed from the contestant backdrops, and the displays are covered by sunbursts of the same color as the respective contestant's arrow with many white, square-edged "beams" spreading out in all directions. A large, gold ring surrounds each sunburst. As the sunbursts are little more than colored filters, they continue to show money put "on account" or total champion winnings with the same limitations.
 * Chuck's Final Spin lands on Bankrupt, to which he responds by mentioning that this is his last week.
 * On December 24:
 * Chuck announces that the next show will be his last.
 * After the game, Chuck and Susan show footage of their visit to New York.
 * "Sleigh Ride" is played during the fee plugs and credits.
 * By December 25 (Claudia/Betty/Sonny):
 * The December 4, 1979 cue is once again used for all commercial breaks, plus the mid-show plug for the airline which flew the players to California.
 * The $2,000 space and the nearby $250 swap positions, resulting in $250 becoming red and $2,000 becoming gold.
 * The first line of the sponsor list is re-centered.
 * December 25 is Chuck's last show. On this day:
 * Susan's entrance includes her blowing kisses to Chuck.
 * There is a commercial break during Round 1, and Chuck erroneously states it has never happened before; one such break occurred on December 24, 1980, and probably other times.
 * During Round 2, Chuck quips that one contestant (possibly Betty) is "the only person I've ever known to hit [Lose A Turn] seventeen times consecutively".
 * After recapping the scores and announcing the winner, Chuck thanks Susan for being a confidant over the previous years; he then thanks Jeff Goldstein, Dave Williger, John Rhinehart, Nancy Jones, Charlie O'Donnell, Jack Clark, Merv Griffin, Murray Schwartz, and NBC. Chuck follows this by admitting that leaving Wheel is "one of the most difficult things I've ever done".
 * No Bonus Round is played, further suggesting the Christmas Wish Bonus may have been a trial run.
 * "We Wish You a Merry Christmas" is played during the fee plugs and credits.
 * As the sponsor list scrolls, Jack mentions that due to a technical difficulty, "a third puzzle was discarded and the program edited".
 * Susan presents Chuck with a gift: a pair of goggles with wipers.
 * December 28 is Teen Week. As with the previous week, the Wheel logo is not used in the opening. Instead, the graphics say "Teen Week on Wheel of Fortune", with "Teen Week" in quotation marks.
 * On December 28 (Jim/Keith/Stacie), Pat Sajak becomes the show's host. On this day:
 * Jack's intro is changed to "Look at this studio, filled with glamorous prizes! Fabulous and exciting merchandise, including [five prizes are described]. Over [amount], just waiting to be won today on Wheel of Fortune!"
 * The curtain begins to descend once again upon the host's entrance. By this point, it only comes down for the hostess' entrance and remains out of sight for the rest of the show.
 * Pat thanks Chuck for hosting the show and wishes him well, then jokes that he is leaving the show as well.
 * The contestant interviews are obviously edited down, perhaps because of Pat's monologue.
 * The camera is zoomed too far back when the board is shown at the start of Round 1.
 * The commercial cues are changed up once again: the electric-guitar cue returns for use during Round 1, during the mid-show catalog plug, and after the Bonus Round, and the December 4, 1979 cue (sounding slightly different) is used during Round 2 and after Round 3. An unknown cue is used following Round 2, as it only plays extremely briefly.
 * Susan turns the hyphen in Round 2 before it lights up.
 * During Round 2, the camera zooms out from the $550 space while an incorrect letter is called.
 * The only vowel bought in the entire game is an A in Round 2.
 * Despite winning Round 2 with $2,650, Jim opts not to buy the $2,195 hot tub, instead purchasing the other 10 prizes in that showcase with the remaining $849 put on a gift certificate. The resulting prize copy runs a solid two minutes, and Pat remarks afterward about Jim not buying the hot tub.
 * The five-and-a-vowel Bonus Round is made permanent. On at least this episode, it is played in front of the yellow sunburst backdrop. The first bonus puzzle under the permanent format is FROSTY THE SNOWMAN; Jim picks T, R, N, S, H, and E as his letters, but does not solve the puzzle.
 * By December 28, the Final Spin rules are slightly altered: rounds that begin as a Speed-Up are almost always played for a gift certificate (or, during this week, a savings bond).
 * By December 28, the Speed-Up split-screen display is reversed to have the puzzle on the bottom and contestants on top. Possibly as a result, the category display is dropped from Speed-Up rounds.
 * As of December 28:
 * The money graphic is still green and still zooms in.
 * Roselon Industries still provides Susan's wardrobe.
 * The "N" of the puzzle font still does not have a top-left serif.
 * Also during Pat's first week:
 * A contestant buys an incorrect vowel, and Pat tells the player to spin again. He is then told by Nancy Jones that the player has in fact lost their turn.
 * A contestant mis-solves the puzzle ABRAHAM LINCOLN as ABRAHAM BINCOLN with only the B and L's missing, to which Pat jokes that Bincoln delivered the Bettysburg Address.

1982
January 1982 :
 * Wheel does not air on January 1 due to the Tournament of Roses parade.
 * Claudia, the returning champion from Chuck's last episode, presumably returns on January 4.
 * There is a Hawaii Week sometime this month, as promoted by Pat during his week on Password Plus and by Variety blurbs on December 22, 1981 and January 8, 1982. This was most likely done identically to the 1981 [City] Weeks, by flying in contestants from Hawaii.
 * On an episode sometime this year, a contestant mis-solves the puzzle IT TAKES ONE TO KNOW ONE as E.T. TAKES ONE TO KNOW ONE with only the I missing.

February 1982 :
 * Around this point, the light-up white trees are replaced by a single green-leaf tree to the left of the turntable.

March 1982 :
 * March 3 is submitted for the Daytime Emmy Awards in regard to a category applying to then-director Dick Carson. This may suggest that the episode, and any others submitted by Wheel, exist.

April 1982 :
 * On April 26, the show moves back to 10:30 AM, replacing Blockbusters.

May 1982 :

June 1982 :
 * Sometime this month, contestant Debi Muchow competes for three shows, winning $15,000 in prizes including 300 square feet of floor tile. Debi is known to have copies of all three episodes in DVD format.

July 1982 :

August 1982 :

September 1982 :
 * By September 2 (Nancy/Beverly/Karen):
 * The opening is slightly altered: Jack now only mentions three prizes, the money graphic becomes white and "flips" toward the camera, and the logo now slides off to the right as Pat is introduced.
 * The puzzle board is slightly altered: the N's now have a top-left serif, while the board itself adds four trilons for a total of 52. As the new trilons are in the corners, they are blocked by the frame and hence cannot be used.
 * "Big Wheels" returns to use for all commercial breaks and the mid-show car/catalog plug.
 * A timpani roll is added to the start of the Bonus Round. The show's logo is projected onto the floor unless the contestant plays for a car, in which case the car is parked in front of the board. (These aspects may have been introduced on January 4.)
 * The Bonus Round is now played from center stage.
 * The credits are slightly changed to show the Wheel spinning below Pat, Susan and the day's champion.
 * On September 2:
 * A four-line puzzle is used for the first known time: Round 2's A LITTLE KNOWLEDGE IS A DANGEROUS THING.
 * For the first known time, a contestant calls R, S, T, L, N and E in the Bonus Round (although not in that order).
 * On September 2 and 3, Pat's Final Spin has the camera start at an overhead shot of the Wheel and zoom in to the red player's arrow (which is not flashing on the 2nd) as the Wheel stops. An identical shot was used on some episodes between December 2003 and January 2004.
 * On September 3 (Beverly/Dorian/Bill):
 * After Susan makes her entrance, Pat makes a remark about her outfit: "Zontar called, he said the invasion of Neptune is off." He makes a few more comments during the post-game chat, then admits he likes the outfit.
 * Just before the first spin, Pat holds up a cue card with a 4 drawn on the back and says "This is the number I drew, and that made me a loser." During the credits, Susan briefly holds up the card and appears to make a comment toward Pat.
 * During Round 1, Pat accidentally tells Bill that L has already been called. He corrects himself a few turns later, saying that the answer simply does not have an L in it.
 * Bill purchases 11 prizes after Round 2; with $1,103 remaining and nothing left to spend it on, he puts it on a gift certificate. The resulting prize copy runs for two minutes and ten seconds.
 * Round 3 begins as a Speed-Up for a Giorgio gift certificate; Pat jokingly blames Reggie Jackson for this, as REGGIE JACKSON was the first puzzle and the segment ran for over nine minutes.
 * Bill sweeps the game and wins a bedroom set in the Bonus Round. The cue used for the bedroom set is the Blank Check theme, also composed by Thicke.
 * Bill calls O in the Bonus Round, the first known instance of a player calling a vowel other than E under the five-and-a-vowel rules.
 * Susan forgets to turn the T in the bonus puzzle GILBERT AND SULLIVAN, and is reminded from offstage.
 * The December 4, 1979 cue is used when going to commercial after the Bonus Round.
 * By September 3, the beginning of the sponsor list is slightly altered to remove the upper-case letters from "or", "to", "the", and "for". A period is also added to the end.
 * By September 3, Climax begins providing Susan's wardrobe; considering the strange outfits she wears on the 2nd and 3rd plus Pat's comments on the latter, this association was probably short-lived.
 * In late September or early October (definitely by October 22), the green-leaf tree is replaced by one which has brown leaves.

October 1982 :
 * As of October 22, the money graphic and logo are still white.
 * October 22 is Susan's last episode, as she wishes to pursue charity work. On this day:
 * To allocate time for Susan's farewell, all of the puzzles are two or three words long.
 * Contestant Kevin wins $2,600, followed by $900 the next Monday. His fiancée appears on the show around the same time, winning $4,400 in one round but not winning the game.
 * At the end of the show, Susan is presented with a bouquet of flowers by Nancy Jones and most of the crew says goodbye to her. The puzzle board shows GOOD-BYE SUSAN on the first three lines.
 * Summer Bartholomew fills in for at least the week of October 25.
 * As of October 27, Wheel draws a 21 share on the Nielsen ratings system. The show following it at this point, Texas, is unable to keep that audience.
 * In late October, and definitely by December 13, the light-up white trees return.

November 1982 :
 * Vicki McCarty and Vanna White (and possibly Summer as well) take turns as guest co-host between November 1 and December 10.
 * November 14 may be Vanna's first taping as guest hostess, based on her comments during certain nighttime shows (namely "three weeks later, I was taping my first [permanent] show").
 * November 18 is Episode #2,000.
 * Wheel does not air on November 25 due to the Macy's Thanksgiving Day Parade.

December 1982 :
 * December 13 is Philadelphia Week, which is the same as previous [City] Weeks minus the returning champion from December 10. The opening shows Pat waving in front of a large fountain.
 * By December 13:
 * The money graphic and Wheel logo begin to be displayed in different colors.
 * The commercial cues are changed up once again: "Big Wheels" is used after Round 1, during the mid-show car plug, and after the Bonus Round; the December 4, 1979 cue is used during Round 2, after Round 2, and after Round 3.
 * The Final Spin shot returns to normal, although the red arrow is again not flashing.
 * December 13 (#2,016; Robin/Louis/Linda) is Vanna's first permanent show, taped December 5. On this day:
 * The Wheel's light layers flash counterclockwise.
 * The category displays are purple, matching Vanna's outfit.
 * Vanna's first official puzzle is GENERAL HOSPITAL, and the first letter she turns is the T.
 * The camera mistakenly holds on a still shot of a curio cabinet after Round 2 while Jack describes it. Later, while describing the final prize bought in that round, the prize cue runs to its end and begins again.
 * Amazingly, neither Bankrupt nor Lose A Turn is hit and no wrong letters are called; the Bonus Round is lost, however. This is believed to be the closest the show has ever come to a "perfect game".
 * Footage from Pat's trip to Philadelphia is shown just before the credits, and this is where Pat signs off.
 * December 13 is the second of only three daytime episodes to be aired by GSN, reran in 2007 as part of the marathon following Merv's death.
 * On at least December 13 and 29, there is a large pot of flowers behind each player.
 * December 27 is Teen Week, with the Friday Finals format. Despite this, the opening for the week (see below) shows 14 contestants; two were likely standby players.
 * By December 27, the normal opening for Teen Week is introduced: three contestants model prizes, followed by all of the week's players sitting or standing in front of the puzzle board (reading TEEN WEEK on the middle two lines); the day's contestants then introduce themselves, followed by Pat and Vanna together.
 * On December 29 (Chris/Evangelina/Jonathan):
 * The contestants stand on boxes, a fact which Pat points out after Round 1. (This may have been the case on other episodes this week, but this is uncertain.)
 * During Round 2, Vanna accidentally turns the O in the puzzle EASIER SAID THAN DONE, but very quickly turns it back while she is still blocking the camera's view.
 * For the first known time, a four-line puzzle is used in the Speed-Up round: THE NINA THE PINTA AND THE SANTA MARIA, also the first known instance of a puzzle being completely revealed before being solved.
 * By December 29:
 * "Big Wheels" is again used for all commercial breaks (except after Round 2 on this episode, as it fades to black before any music can begin).
 * The red arrow again flashes during the Final Spin.
 * Pacino begins providing Vanna's wardrobe.

1983
January 1983 :
 * On January 3, the show moves back to 11:00 AM.
 * The January 20 show is Episode #2,044, taped January 9.
 * As of January 20, the turntable still looks the same as it did on December 21, 1981.

February 1983 :
 * Around this point (definitely after January 20), the on-set trees become green again. This time, however, there are two such trees.
 * On an episode sometime between the return of the green-leaf trees and August 5, Pat reads a letter during the final segment from a viewer who gave birth while watching Wheel, solving the puzzle DOBERMAN PINSCHER very shortly before the child was born (11:11, putting that episode no earlier than January 3). Clips from this segment appear during the intro on April 19, 2013.

March 1983 :
 * March 28 is Teen Week, with the Friday Finals format. The winner of the week plays the Bonus Round for a $5,302 vacation for four to Disneyland.

April 1983 :
 * On April 1 (Trevor/Juanita/Michelle):
 * During Round 1, both a ding and the applause machine abruptly cut off after the I's are purchased.
 * No music is played during the commercial outro after Round 2, as it fades to black too quickly.
 * Five rounds are played, a more unusual event than on March 25, 1980 due to the presence of the Bonus Round. Like the Armed Forces episode in 1981, $1,000 is the top value for Rounds 3-4 and $2,000 for Round 5.
 * Trevor mis-solves the Round 3 puzzle JUICE NEWTON as JOYCE NEWTON. A turn later, the "only vowels remain" beeps fail to sound, although a stagehand can be heard telling Pat that only vowels remain. Juanita then solves the puzzle for $50.
 * After the Bonus Round (which is not won), Pat gives the player a hamburger "garnished" with two $100 bills. She is then awarded five hours of a chauffeured stretch limo, which drives out from behind the host's area and stops in front of Pat; the driver gets out and opens the back door, revealing Vanna, after which all of the Teen Week contestants come onstage.
 * By April 1, the December 4, 1979 cue returns for at least one commercial break (in this case, after Round 5) as well as after the Bonus Round.
 * By April 1, New Leaf begins providing Vanna's wardrobe.

May 1983 :
 * The May 6 show is Julie/Shirley/Barry.
 * On an episode sometime this month, possibly a Tuesday and definitely before May 23:
 * The Wheel's spikes are re-welded with a new method that makes the spins much quieter than they were previously (referred to by Pat the next day as "the 10,000-spin checkup").
 * A champion retires undefeated.
 * On an episode sometime this month (Jackie/Penny/Paul), known to be the day after the above (and according to one recollection, "ten days" after the May 6 show):
 * During the open, Pat honks a car's horn right after Jack introduces him.
 * Pat does the opening spin with both feet off the floor. Following the overhead Wheel shot, the camera returns to the position it had just before.
 * Before Round 2, the puzzle chime accidentally sounds while Pat talks about the aforementioned Wheel update. It later sounds again in its proper place.
 * After the Round 2 puzzle STEPHANIE POWERS is solved, the O does not light up at first. Vanna merely stands in front of it, apparently waiting for it to light up, then looks to her right and turns the trilon anyway. The O does not light up until after the puzzle is fully revealed.
 * During Round 3, Paul calls for either A or H (already in the puzzle) and stops himself halfway, then says S. Pat briefly consults the judges, after which Paul is credited with the S, which is not in the puzzle.
 * Pat's Final Spin lands on Lose A Turn.
 * After Round 3, Penny's score display goes blank; the dollar sign on Paul's display is still present.
 * There are two sets of repeated categories: Phrase in Rounds 1 and 3, Person in Round 2, and People in the Bonus Round.
 * By the above episode, the commercial outro cue pattern is changed once again: "Big Wheels" is played after Round 1, during Round 3, and during the mid-show catalog plug; the December 4, 1979 cue is played after Rounds 2 and 3 plus after the Bonus Round.
 * By the above episode, Climax begins providing Vanna's wardrobe; unlike the period where the company provided Susan's wardrobe, it is now credited as "Climax of California".
 * The Vacation Bonanza Contest (the first known home viewer sweepstakes) is held from about May 16 until sometime afterward. A print ad promoting said contest explains that home viewers "play Wheel of Fortune from [their] own home" for "an exotic dream vacation", with Hawaii specifically mentioned.

June 1983 :

July 1983 :

August 1983 :
 * On August 8, Alan Thicke's music package is replaced with a new one composed by Griffin and Mort Lindsey, including a new theme tune called "Changing Keys". The last three notes of "Changing Keys" are also the cue for solving a puzzle.
 * Shopping rounds use a music cue called "Nightwalk" as the contestant buys prizes, and a variety of cues for the prize descriptions (including "Frisco Disco", the closing theme of the 1978-79 Jeopardy! revival).
 * "Changing Keys" is also used for all commercial breaks, ending a three-year period where Thicke's three commercial cues ("Big Wheels"; December 4, 1979; and electric-guitar) were generally inconsistent in their use.
 * For its first year of use, "Changing Keys" is cued up at the 0:56 mark during the intro. The bridge also plays when Vanna walks out, although the nighttime show replaces it with "I'm a Wheel Watcher" on October 5, 1987. The instrumentation is also more "chirpy" for the first few months.
 * With the introduction of "Changing Keys", the intro is changed to start with an overhead shot of the spinning Wheel, with the logo zooming into its center accompanied by a pre-recorded "Wheel! Of! Fortune!" chant by an audience. It is somewhat similar to the overhead shot used from the 1974 pilots through at least November 3, 1975.
 * Presumably at the same time, and definitely by the first nighttime tapings (see below), the turntable is altered to add flower-esque emblems to the curved top-left and top-right portions of all three sides.
 * Also presumably at the same time, and definitely by the first nighttime tapings, the beginning of the sponsor list becomes yellow.
 * As of August 10, Wheel draws an 7.2 on the Nielsen ratings system with a 30 share.

September 1983 :
 * The nighttime version debuts September 19 in most markets, between August 29 and September 12 in others. An old version of the show's website considered September 5 to be the "official" debut date.
 * In late September, the money graphic and subsequent logo begin using white outlines; previously, they were black.
 * In late September or early October, the on-set trees become brown again.
 * As of September 23, Wheel draws a 5.8 on the Nielsen ratings system with a 29 share.

October 1983 :
 * On October 31 (Tina/Janet/Tim):
 * During Round 1, Pat forgets to ask Tim if he wants to use his Free Spin.
 * After Round 1, the transition to the turntable is that from the opening, and briefly "sticks" halfway.
 * Jack's prize description after Round 3 ends abruptly following the last item, with the "s" in "dollars" being cut off.
 * There are two sets of repeated categories: Phrase in Round 2 and the Bonus Round, Thing in Rounds 3 and 4.
 * The bonus puzzle WIN LOSE OR DRAW is the first known instance of a bonus puzzle using all four lines of the puzzle board, although the answer would have easily fit on two.
 * Following the Bonus Round, Pat and Vanna plug the Home Puzzle Contest. An unaired outtake from this segment appears at the end of the ceremonial 4,000th nighttime show in 2003.
 * By October 31:
 * The on-set trees begin using their light-up white appearance again.
 * A bumper is added at about the middle of each episode, showing the turntable spinning into place for the next round with a Wheel of Fortune logo slightly above the center of the screen. Said logo is in a different shape and font than any "official" logo (including the one in use at this point), and is displayed in various colors sometimes (but not always) matching the money graphic and opening logo.
 * The beginning of the sponsor list becomes white again.
 * Jon Wesley begins providing Vanna's wardrobe.

November 1983 :
 * November 1-4 are the Home Puzzle Contest, where portions of a puzzle are revealed each day. The winners receive a microwave oven with accessories, a set of kitchen appliances, or a "video package" including a television and a videotape recorder.
 * November 7 is likely the first Couples Week, with husband/wife teams ranging from engaged to married for 40 years. This week uses the Friday Finals format, with the winning couple on Friday playing the Bonus Round for a 1984 "American luxury car". The opening shot of the puzzle board has COUPLES WEEK on the middle two lines.
 * On November 9 (Bill & Kathy/Don & Susan/Frank & Debbie):
 * The money graphic is a flipping version of the green one used through at least Pat's first day.
 * Oddly, the opening shot of the puzzle board shows just eight couples, suggesting it was redone for each episode as couples were eliminated.
 * During Round 1, Bill & Kathy's score display goes out twice: once during the round, and again after the puzzle is solved. The display does not return by the commercial break. (They are the only couple to play Round 1.)
 * Pat is shown in the chroma-key circle after Round 3.
 * In an extremely-rare event, all four puzzles are Phrase.
 * Bill & Kathy fail to solve the bonus puzzle TOP SECRET with the O, P, and C missing, after which Bill remarks "Oh, that was so easy!"
 * By November 9, the mid-show bumper logo is enlarged and moved to the top of the screen.
 * By November 9, Giorgio of Beverly Hills begins providing Vanna's wardrobe.
 * Wheel does not air on November 24 due to the Macy's Thanksgiving Day Parade.
 * On November 28, the Merv Griffin Productions logo is replaced by a full-color drawing of a griffin against a black background.

December 1983 :

1984
January 1984 :
 * Wheel does not air on January 2 due to the Tournament of Roses parade.
 * On an episode sometime this month (Lynn/Doug/Cathy):
 * The Wheel spins very slowly during the opening.
 * Before Round 2, the applause machine sounds at its loudest setting while Pat mentions the presence of two apostrophes in the puzzle.
 * During Round 2, two players in a row call a letter that is already in the puzzle; against precedent, the buzzer sounds on both.
 * During the Speed-Up round, Doug forgets to say the last syllable of NEW DELHI INDIA. Oddly, the camera cuts to a close-up of him as he says the correct answer.
 * By the above episode, the puzzle board's chase light sequence is occasionally reversed: the left side now goes clockwise and the right counterclockwise. As far as is known, episodes used either the original sequence or the reversed one; never both.
 * As of the above episode, the set still looks the same as it did on December 21, 1981.
 * Drew Pinsky is a contestant sometime this year (before the sunburst backdrops change), although he does not solve any puzzles. Brief clips were shown on a September 2011 episode of The Ellen DeGeneres Show when Pinsky (since risen to fame as "Dr. Drew") appeared as a guest, although the episode itself does not appear to circulate.

February 1984 :
 * Early this month, the on-set trees are replaced by walls with foliage on them. The walls change according to the time of year (using snowflakes and lights in Winter), while the trees continue to appear occasionally.
 * Sometime this month, and definitely by the 27th, the Griffin logo is altered: the text is now much smaller and uses the Peignot font, while the griffin no longer blinks. At least some nighttime episodes from this point through April use the animated griffin with the smaller text, and at least one taped in March has the old animated logo from November.
 * February 27 is probably the first Battle of the Sexes week. The Monday-Thursday games each feature three women or three men playing, with the top winner of each gender playing on Friday for a shot at $5,000 in the Bonus Round.
 * The opening for Battle of the Sexes shows the week's contestants playing a tug-of-war in front of the puzzle board, which reads BATTLE OF THE SEXES on the middle two lines. There are six men and seven women, indicating that one of the ladies was a standby.
 * On February 29 (Ron/Ray/Rick):
 * The Wheel spins very slowly during the opening and credits.
 * The puzzle board uses its reversed chase light sequence.
 * Before Round 2, Pat brings up a question from Ray, who thought Pat was in the film "Raiders from Outer Space" (actually an episode of the 1960s anthology series The Time Tunnel). Pat remarks that he does not recall such a role, and it was probably another game show host. Pat and Vanna discuss this a bit further after the Bonus Round.
 * The Round 2 puzzle is SARAH PURCELL, co-host of the 1977-78 game show The Better Sex. While the use of her name as a puzzle during this particular week is likely a coincidence, it is still interesting to note.
 * There are two sets of repeated categories: Phrase in Rounds 1 and 4, Thing in Round 3 and the Bonus Round.
 * Pat and Vanna can be heard talking during the credits.
 * As of February 29, the beginning of the sponsor list still looks the same as it did on October 31.
 * By February 29, Jon Wesley begins providing Vanna's wardrobe again.

March 1984 :
 * As of March 21, Wheel draws an 8.1 on the Nielsen ratings system with a 31 share, a 6-share increase since the beginning of 1983.

April 1984 :
 * Around this point, the static small-text Griffin logo begins to be used permanently.
 * On a Thursday episode between April 12 and May 24 (Staa/Nickie/Bill):
 * During his interview, Bill accidentally calls Pat "Jack". After Round 1, Pat refers to Jack as "Pat".
 * The puzzle board uses its reversed chase light sequence.
 * During Round 3, it takes six spins before a correct letter is called.
 * There are two sets of repeated categories: Phrase in Rounds 1 and 2, Thing in Rounds 3 and 4 plus the Bonus Round.
 * Pat signs off immediately after the Bonus Round.
 * No overhead Wheel shot is used during the credits.
 * By the above episode, the beginning of the sponsor list returns to having the first letter of each word capitalized.
 * By the above episode, Climax begins providing Vanna's wardrobe again.
 * As of the above episode, the mid-show bumper logo still looks and acts the same as it did on November 9, 1983.

May 1984 :

June 1984 :

July 1984 :
 * Sometime in this month or August, there is a week with U.S. Olympic athletes playing for charity.

August 1984 :

September 1984 :
 * By September 10, at Merv's insistence, contestants generally stop using "as in" when calling letters (e.g., "P as in Pat.") unless necessary for clarification.
 * On September 10, the Griffin logo is altered to replace "Productions" with "Enterprises". Subsequently, Jack's closing spiel is now "Wheel of Fortune is produced by Merv Griffin Enterprises."
 * Most likely on September 17, "Changing Keys" is re-orchestrated slightly. A glissando is added to the beginning, and the instrumentation is less "chirpy". The theme now begins at the first bar during the intro, instead of the 0:56 mark. The original version continues to be played during the mid-show prize plugs through the end of June 1989.
 * Celia/Joseph/Gloria airs on a Monday sometime between the introduction of the 1984 "Changing Keys" and that of the second sunburst backdrops, most likely September 17 or 24. On this episode:
 * Pat mentions that Celia purchased a car the previous Thursday, then won a second in the Bonus Round the next day.
 * The puzzle board uses its reversed chase light sequence.
 * In a rarity, only one prize is bought after each of the first two rounds.
 * Two sets of repeated categories are used: Round 1 is People, Round 3 is Person, and Round 4 and the Bonus Round are Thing.
 * An upcoming Teen Week is plugged.
 * By the above episode, the mid-show bumper logo returns to its style from October 31, 1983.
 * By the above episode, Pacino begins providing Vanna's wardrobe again.

October 1984 :
 * Most likely on October 1, the squared-off edges of the contestant backdrops become pointed; the outer edge is now dark brown, while the area immediately surrounding the player's color is changed to light brown.
 * At this point, there is still a $150 wedge next to $1,000 in Round 2.

November 1984 :
 * Wheel does not air on November 22 due to the Macy's Thanksgiving Day Parade.
 * By November 23, the $150 next to $1,000 in Round 2 is decreased to $100.
 * A Battle of the Sexes week is held sometime between November 26 and December 10, played the same way as the week in February.
 * The opening is slightly altered to have BATTLE OF THE SEXES on the first three lines of the puzzle board. There are seven men and seven women, indicating that one of each was a standby.
 * On the Thursday show of the above week (Jeanne/Stephanie/Terri):
 * The puzzle board uses its reversed chase light sequence.
 * The category displays are purple, matching Vanna's outfit.
 * Stephanie puts $15 "on account" following Round 1, but loses it to Bankrupt in Round 2.
 * The commercial outro of Round 1 is the 1983 "Changing Keys", which is also used for the mid-show Service Merchandise plug. The former begins it at the 0:56 mark, while the latter starts it from the beginning.
 * The players are shown turning their backs as Pat throws to commercial during Round 2.
 * Vanna turns a trilon too far during Round 3, causing the sheet to partly slide out of the trilon.
 * Later in Round 3, Jeanne spins just as the Final Spin chimes sound; she is allowed to complete her turn, although the camera remains on the Wheel shot as she calls her letter. When it changes to the board (right after Vanna turns the first F), the shot is not centered and does not show the category. The camera then shows Jeanne and her score as Pat begins the Final Spin, which quickly changes to the normal shot of him doing so.
 * The bonus puzzle HEAVEN ON EARTH is the first known appearance of Quotation in the Bonus Round.
 * No overhead Wheel shot is used during the credits.
 * During the credits, Jack notes that "Due to a technical difficulty, a spin in the third round was recreated and the program edited." This refers to the aforementioned spin, given the odd directing work during that portion of the show.
 * As of the above episode, the mid-show bumper logo still looks and acts the same as it did in mid-September.
 * By the above episode, and definitely by December 19, the Winter decorations are added to the walls.
 * By the above episode, New Leaf begins providing Vanna's wardrobe again.

December 1984 :
 * The December 19 show is Dolly/Robert/Connie.

1985
January 1985 :
 * Wheel does not air on January 1 due to the Tournament of Roses parade.
 * Sometime this month, likely around January 21, three graphical changes are made:
 * The logo used at the beginning of the show becomes a chyron with white borders and letters which are closer together than the previous logo. The transparent portions of the Wheel graphic are filled in, while the formerly-filled spaces become white.
 * The logo shown after the money graphic is updated to an animated one with colored sections rotating in the center (colors which, at this point, vary). The letters and dots flash in dark and light shades of yellow.
 * The monospaced category displays become chyrons in a medium form of Helvetica, often in burnt orange. The Bonus Round totals and credits also begin using Helvetica.
 * Later in January, the category chyrons get a shadow effect. Slightly later, the regular animated logo (with red, blue, green, and yellow sections) debuts.
 * At this point, the credits are still white.

February 1985 :
 * By February 8 (Warren/Sol/Linda):
 * The category chyrons and Bonus Round totals are upgraded to a bolder form of Helvetica with no shadow and a white outline around the bottom of each character. They again display in various colors, often matching Vanna's outfit (with the exception of neutral colors such as black, white, brown, and gray).
 * The Winter decorations are again removed from the walls. This is uncertain, however, as there are several nighttime episodes with the shadowed category chyrons but no Winter items and a couple with the Winter items and second chyrons.
 * The graphics for the eligibility disclaimer, wardrobe plugs, and full credit roll become blue; previously, they were white.
 * The mid-show bumper begins spelling out the show's title one letter at a time horizontally.
 * On February 8:
 * The puzzle board uses its reversed chase light sequence.
 * Rounds 1, 2 and 4 are Phrase.
 * No overhead Wheel shot is used during the credits.
 * February 11 is Couples Week. Wheel10thanniversary.png
 * Sometime this month, most likely the week of February 18, the show celebrates its 10th Anniversary with a week-long home-viewer contest.

March 1985 :
 * By March 29 (Linda/Mary Ann/Larry), the category chyrons are altered again to have the white outline around the entirety of each character, a style which remains for the rest of the run.
 * Sometime between the introduction of the third Helvetica chyrons and that of the third sunburst backdrops, a then-unknown Jean-Paul Manoux is a contestant (as "J.P.") during Teen Week and wins $9,020: $2,650 in the front game and a $6,370 trip to Tahiti in the Bonus Round.
 * On an episode sometime between the introduction of the third Helvetica chyrons and the Wheel's color scheme overhaul in September 1986, a then-relatively unknown Douglas Puffert is a contestant. He wins at least $5,800, and it is known that his winnings include a car (although whether this was part of the $5,800, won in the Bonus Round, or purchased on the next episode is unknown).

April 1985 :
 * On April 1, Pat makes an April Fool's joke by claiming that he and Vanna are married.
 * The April 24 and 25 shows are Mary/Mirtha/Chuck and Chuck/Norma/Shira, respectively.

May 1985 :
 * As of May 2, the Bankrupt slide whistle is still heard if Pat hits it on the Final Spin.

June 1985 :
 * At this point, the beginning of the sponsor list still looks the same as it did in Spring 1984.
 * The June 5 show is Rebecca/Kerry/Edna.
 * Karen/Robert/Rachel airs on June 18 or 25.
 * On June 19 or 26 (Pamela/Tracie/Robert), Pamela sweeps the game and wins a station wagon in the Bonus Round.
 * At this point, the Griffin logo still looks the same as it did on September 10, 1984.

July 1985 :

August 1985 :
 * Alex Trebek fills in for Pat sometime this month, most likely for one episode.

September 1985 :
 * By September 9, the Griffin logo is altered slightly: the font color is now pacific blue, rather than the silver used previously.
 * The September 23 show is James/Karla/Yvonne.

October 1985 :

November 1985 :
 * Wheel does not air on November 28 due to the Macy's Thanksgiving Day Parade.

December 1985 :
 * By December 5, the beginning of the sponsor list returns to solely using upper-case letters.
 * Sometime this month (after the 5th), the Winter decorations likely return to the walls.
 * On December 25, Jack appears onstage at the end of the show with Pat and Vanna to wish everyone a Merry Christmas.

1986
January 1986 :
 * Wheel does not air on January 1 due to the Tournament of Roses parade.
 * Nick/Rebecca/Corky possibly airs sometime this year. It is known to have the Winter decorations, but does not air on a Monday.

February 1986 :
 * Sometime this month, the Winter decorations are again removed from the walls (assuming they were added in the first place).

March 1986 :
 * Wheel likely becomes closed-captioned for the hearing-impaired on March 6, the same day the nighttime version does so, but this is uncertain.

April 1986 :

May 1986 :

June 1986 :
 * June 16 is Teen Week. Susan Stafford returns for this week, filling in for Vanna (who is absent due to a then-recent plane crash which killed her fiancée, John Gibson).
 * On June 20 (Peter/Aurora/Wendy):
 * The puzzle board uses its reversed chase light sequence.
 * The game is played for savings bonds, with no shopping.
 * There are two sets of repeated categories: Phrase in Round 1 and the Bonus Round, Things in Round 3, and Thing in Round 4.
 * No credit is given for Susan's wardrobe. This may have been the case on the other shows this week, but this is uncertain.
 * By June 20, and likely much earlier, "VIDEOTAPED AT NBC STUDIOS Burbank, California" is added to the end of the full credit roll.
 * As of June 20, $175 is still present on the Wheel and $1,500 is still on the right-hand side of Bankrupt.
 * On June 23, Vanna tells Pat at the end of the show that she went on a vacation, after which she gives him several gifts that she found for him.

July 1986 :
 * On July 16 (Ray/Randy/Gary):
 * Three males play.
 * The bonus puzzle EQUATOR is inexplicably categorized as Thing instead of Place.
 * On another episode sometime this month (known to have the bonus puzzle ELECTRICIAN), the puzzle board uses its original chase light sequence.

August 1986 :
 * On an episode during the Summer:
 * The yellow contestant acquires five Free Spins and uses all five in Round 2.
 * Round 3 starts as a Speed-Up and, thanks to a $2,000 Final Spin, the blue contestant ends up winning despite having not touched the Wheel at all.

September 1986 :
 * Around this point, Pat has generally stopped saying "For [amount], [solve/identify/what's] this [category]" when a contestant asks to solve a puzzle. JackpotDaytime.jpg
 * By September 8, the Wheel wedges are considerably recolored, most noticeably replacing most of the tan and gold with pink and purple. In addition, $175 is retired (replaced by $500) and $1,500 moves to the opposite side of Bankrupt.
 * September 15 is the debut of the Jackpot wedge, which begins at $1,000 and increases by $1,000 each day until claimed. It is treated as a Prize wedge, and hence cannot be spent on vowels or in shopping rounds. This is perhaps the first time cash is offered on the daytime show as a regular element since the hour-long era ended in 1976.
 * If the Jackpot is not won at $1,000, Jack's opening spiel is altered to begin with "Look at this studio, filled with glamorous prizes! Fabulous and exciting merchandise, including a(n) $x,000 cash jackpot!" The opening money graphic for the Jackpot simply zooms in, then flashes.
 * The wedge is not used during "special" weeks (Teen, College, Battle of the Sexes, etc.), most likely due to the Friday Finals.
 * From this point until its retirement, at least some dates that mention a Jackpot win without an amount are guesses.

October 1986 :
 * October 3 is Episode #3,000, taped around September 19. The Encyclopedia of TV Game Shows: Volume 2 includes a photo of Pat and Vanna at the puzzle board, which reads WHEEL OF FORTUNE'S 3000TH SHOW (with the numbers in a different font than the letters).
 * As of mid-October, the contestant backdrops are still look the same as they did around October 1984. Sometime between then and November 13, they are altered to streamline the "jagged" edges; the resulting appearance closely resembles a sunflower.
 * As of mid-October, the walls introduced in early 1984 are still present. Sometime between then and November 13, they are replaced by a set of lights and a more colorful background.
 * On a Monday episode from the Fall (Dean/Kathy/Karen), after the third sunburst backdrops are introduced and the walls are dropped:
 * The puzzle board uses its reversed chase light sequence.
 * Only one prize is bought after Round 1: a $350 collection of Pressman board games, including Deluxe Wheel of Fortune.
 * The Jackpot graphic is a collection of gold coins and a gold bracelet; the money graphic, which resembles that from the opening, is red and flashes.
 * The bonus prize, a $4,200 cabinet, is presented next to the puzzle board.
 * By the above episode, Gucci begins providing Vanna's wardrobe.
 * An episode sometime in late October or early November (after the aforementioned set changes) has a Jackpot win; the contestant, Bernice, ends the game with $16,050 and wins a car in the Bonus Round.
 * On the above episode and at least one other in the same taping session, the puzzle board uses its reversed chase light sequence.

November 1986 :
 * November 10 has a Jackpot win.
 * On November 13 (Mike/Jill/Dawn):
 * The puzzle board uses its original chase light sequence.
 * In Round 1, Mike accidentally calls a vowel instead of a consonant after a spin.
 * The players are shown turning their backs as Pat throws to commercial during Round 2.
 * The Jackpot graphic is a gold "Horn of Plenty" with various coins around it; the money graphic is gold and stationary.
 * The game ends in a tie. As a result, no Bonus Round is played and all three contestants continue on the 14th. The returning champion, who is not one of the tied contestants, is told that the next day's game will be a "continuation of [her] second appearance". In place of the Bonus Round, Pat and Vanna converse, and Pat shows the device from which contestants draw numbers to determine who starts the game.
 * Climax provides Vanna's wardrobe.
 * As of November 13, the Enterprises logo still looks the same as it did on September 10, 1984.
 * November 17 is College Week. JackClarkBackstage10-1986.jpg
 * At around this point, Jack still does his announcing work in an offstage utility room.
 * Wheel does not air on November 27 due to the Macy's Thanksgiving Day Parade.

December 1986 :
 * On December 11, contestant Stanton Keeney retires with $49,633. He solves all but one main-game puzzle and wins all three Bonus Rounds.
 * As of December 11, the Used Letter Board is still a chalkboard.
 * December 22 is Teen Week, taped November 22. During this week:
 * The opening, using the same structure as previous Teen Weeks, shows 13 players in front of the puzzle board (Guru does not play at all this week). The participants are seen "modeling" the prizes at the top of the show.
 * As it is also the week of Christmas, a large bow is present on the puzzle board's frame and each of the pillars flanking the turntable. The contestant area also has a small decoration behind each player.
 * The animated Wheel logo is not used.
 * Pat Richards provides Vanna's wardrobe on the 22nd, and Climax on the 23rd and 24th. It would appear that by this point, there are several rotating sponsors for her outfits.
 * The puzzle board uses its original chase light sequence on at least the 22nd, 24th, and 25th.
 * On December 22 (Chrissy/Tom/Danny):
 * Pat mentions debuting a new video by him and Vanna "later in the week".
 * "We Wish You A Merry Christmas" is played during the Round 2 prize descriptions.
 * The Bonus Round timer continues to play for about two seconds after the time's-up buzzer.
 * The top winner has only $1,900, and all three players combined have only $2,700.
 * The Wheel can be heard loudly spinning as Pat and Vanna sign off.
 * By December 22, the Enterprises logo adds "A unit of The Coca-Cola Company" between the Enterprises logo and copyright date. The December 22 shot begins with a closeup of this text before zooming out, suggesting that this is the first episode with the credit.
 * The December 23 show (Jim/Tracey/Carol) is mostly pre-empted on the East Coast by an NBC News report (the Voyager successfully returning to its base after a nine-day nonstop flight around the world), rejoining just before Jack begins the Round 3 prize descriptions. West Coast viewers see the entire episode. Among the known events:
 * During the Bonus Round, Tracey's call of M is misheard as N, and the N is briefly put on the chyron.
 * Afterward, one of Tracey's relatives accidentally gets herself caught on the player's microphone.
 * The opening logo-on-Wheel shot accidentally appears very briefly before the camera switches to the Merv Griffin logo.
 * On December 24 (Kathy/Leslie/Victor):
 * The opening Wheel shot suddenly jumps backward when the transition appears.
 * During Round 2, Pat forgets to ask Leslie if she wants to use her Free Spin. He does this again in Round 3, but she turns it in herself.
 * The players are shown turning their backs at the break during Round 3.
 * On December 25 (Valerie/Ian/Paula):
 * While doing the opening spin, Pat accidentally says $450 is top dollar for Round 1 instead of $750.
 * Ian tries to spin during the Speed-Up, but is stopped before he can do so.
 * After Pat and Vanna's sign-off, the puzzle board is shown with the words MERRY CHRISTMAS on the middle two lines. "We Wish You a Merry Christmas" is played from here through the end of the credits.
 * On at least December 25, and probably for the entire week, the mid-show bumper is a shot of the TEEN WEEK board and players; the logo animation is much faster, and has green lettering.
 * The December 26 show appears to have been pre-empted by most of the network in favor of either sports programming or, on at least one affiliate (WXIA in Atlanta, Georgia), a soap opera. The soap is likely the series finale of Search for Tomorrow, which had been airing at 12:30 since it moved from CBS in March 1982.

1987
January 1987 :
 * Wheel does not air on January 1 due to the Tournament of Roses parade.
 * At some point this year, two games in a row end in a tie. This results in a champion playing five games.
 * On an episode sometime this month (Mitzi/Tony/Cheryl), the puzzle board uses its original chase light sequence.

February 1987 :
 * For the entirety of this month, Wheel and NBC's other game shows (Blockbusters, $ale of the Century, Scrabble, Super Password, and Wordplay) participate in the "Car-azy February" Sweepstakes; on Wheel, certain episodes have a special puzzle for home viewers to solve by sending their guesses via mail. The answers and car winners are revealed on-air around the beginning of March.
 * February 9 is Battle of the Sexes Week. The open is the same as in 1984, with the genders' positions swapped and the puzzle board reading BATTLE OF THE SEXES on the top three lines; oddly, there are eight women and seven men.
 * By February 12, the puzzle board's chase lights begin using the reversed sequence permanently, and this remains so for the rest of the daytime run.
 * The February 13 show is Mike/Renee.

March 1987 :
 * March 13 has a Jackpot win.
 * On March 16, contestant Clay sweeps the game and wins the Bonus Round.
 * As of March 17 (Phyllis/Alan/Clay), the money graphic still acts the same as it did on September 2, 1982.
 * On March 17:
 * Due to it being St. Patrick's Day, Pat wears a frog hat from shortly after Vanna's entrance through the end of the show. A close-up of Pat wearing the hat appears in the ceremonial 3,000th and 4,000th nighttime shows.
 * After the ceramic Dalmatian is bought, Jack refers to it during his prize descriptions as the show's mascot.
 * There is a $2,000 Jackpot win.
 * March 19 also has a Jackpot win.
 * By March 30 (Randy/Robin/Jim), the money graphic begins zooming in much like the Jackpot graphic, and appears at the top of the screen.
 * By March 30, Jack begins announcing from a "booth" in front of the audience. This setup remains through at least mid-October 1988, and likely through June 30, 1989.
 * On March 30:
 * It takes six turns to reveal any letters in the Round 1 puzzle HO CHI MINH. The puzzle is then mispronounced by Jim with only the O unrevealed, after which Randy solves for the $200 house minimum. 15 turns are lost in this round including a Bankrupt, an incorrect E, and the aforementioned missolve.
 * After Randy buys the ceramic Dalmatian following Round 1, Pat immediately puts the remaining $46 on a gift certificate without offering the option to put it on account.
 * Randy sweeps the game, but loses a Mazda in the Bonus Round. Her total of $1,000 is one of the lowest winning scores in the show's history, and very likely a record low for total winnings among an episode's players. The total amount of prizes purchased (three, one in each round) is also very likely a record low.
 * Pat and Vanna talk to Jack during the final segment. Before introducing him, Pat notes that Jack had been in an offstage room for years and the new setup had debuted "only recently".

April 1987 :
 * On April 1 (Steven/Gail/Missy)
 * The blanks of the Round 3 puzzle are not shown until after Missy begins her first spin.
 * The footage of the trailer the winning contestant plays for is either prerecorded or followed by an edit, as it is followed by a fade to the normal "dimming lights" puzzle board shot with Vanna next to the trilons despite the fact she had just been modeling the trailer.
 * During the final segment, Pat and Vanna talk about the April Fool's joke they played two years earlier.
 * The Wheel can be heard starting its automation as Pat and Vanna sign off.
 * April 16 has a Jackpot win.
 * On April 27 (Pete/Carolyn/Elaine), the puzzle board reads BEAST during the credits. This was done, presumably by Pat, by rearranging the letters in the bonus puzzle BEST MAN. He is known to have scrambled the bonus puzzle on at least two other occasions.
 * As of April 27, commercial breaks may still occur during a round (Round 2 in this case).

May 1987 :
 * May 7 has a Jackpot win.

June 1987 :
 * June 5 and 8 are the first known instance of two consecutive Jackpot wins, the former being $21,000.
 * The June 9, 12, and 15 shows are Carmen/Kelley/Mark, MaryKay/Ted/Kim, and Rod/MaryKay/Angie respectively.
 * On June 17, Pat and Vanna chat with Jack at the end of the show.
 * At this point, the category chyrons are still not present during Speed-Up rounds.
 * At this point, the Enterprises logo still looks the same as it did on December 22, 1986.

July 1987 :
 * Most of this month's episodes are pre-empted due to coverage of the Iran-Contra affairs.

August 1987 :

September 1987 :

October 1987 :
 * By about mid-October, the category chyrons begin to appear in Speed-Up rounds.
 * By about mid-October, the Enterprises logo is altered: the background becomes yellow, and "A unit of The Coca-Cola Company" is changed to "A unit of Coca-Cola TELEVISION".
 * As of about mid-October, The "only vowels remain" beeps still sound eight times.
 * October 28 probably has a Jackpot win.

November 1987 :
 * By about mid-November, the "only vowels remain" beeps are shortened from eight to four.
 * Wheel does not air on November 26 due to the Macy's Thanksgiving Day Parade.
 * November 27 and 30 are the second known instance of two consecutive Jackpot wins, this time by the same contestant. Pat states on the 30th (Dave/Diana/Susan) that the November 27 Jackpot was $22,000, which is the highest known total ever achieved by it.
 * On November 30, following the latter Jackpot win and Jack's prize plugs, Pat is seen holding the wedge upside-down and calling it the Topkcaj. Much later, in 1996, Pat uses the same joke to introduce the nighttime Jackpot.

December 1987 :
 * Sometime this month, contestant Robert Forst loses $10,800 by adding "the" in front of ATLANTA FALCONS. He ends up with no money, leaving with $4,800 from his previous game.
 * December 21 is Teen Week, with the Friday Finals format. During this week:
 * As in 1986, the opening shows all 15 participants standing or sitting at the puzzle board.
 * The set is again decorated for Christmas.
 * On December 21 (Joey/Steve/Samantha):
 * The mid-show bumper logo is still in use.
 * For the last known time, the chroma-key Wheel shot is used during Pat and Vanna's sign-off.
 * On December 25:
 * The main game is played for savings bonds, with no shopping.
 * "We Wish You A Merry Christmas" plays from Pat and Vanna's sign-off through the end of the credits.
 * No overhead Wheel shot is used during the credits.
 * As the wardrobe plugs appear, Jack wishes the home viewers a Merry Christmas. As a result, he technically signs off by name, the first known instance of a daytime announcer doing so.
 * As of December 25, the beginning of the sponsor list still says the same thing it did on December 28, 1981.
 * Beginning December 28, the fee plugs are eliminated. Departing contestants now receive a substantial prize, announced before the beginning of Round 3 or 4, per NBC's wishes.
 * Most likely at this point, and definitely by October 26, 1988, the beginning of the sponsor list changes to "THE FOLLOWING HAVE FURNISHED PRIZES FOR PROMOTING THEIR PRODUCTS."

1988
January 1988 :
 * Wheel does not air on January 1 due to the Tournament of Roses parade.

February 1988 :
 * On February 8, the Enterprises logo replaces "A unit of Coca-Cola TELEVISION" with "A unit of Columbia Pictures Entertainment, Inc."
 * On February 24, The Pat Sajak Show is announced by CBS. Likely at the same time, Pat announces his eventual departure from the daytime show.

March 1988 :

April 1988 :

May 1988 :
 * May 6 is likely Jack's last episode, with Charlie O'Donnell filling in afterward.
 * Around this point, contestant Debra Stuker plays for two or three shows, winning $36,829 (including a Jeep, sailboat, small motorboat, artwork, sportswear, TV, VCR, jukebox, and sporting equipment). Much later, at the end of August 1989, the Associated Press reports that while some of her prizes arrived respectably (including the Jeep, traded in for a van), the $4,200 jukebox and $10,000 boat were both delivered in very poor condition. At the time of the article, the show took back the boat without offering a replacement and offered $2,500 cash (not taken) instead of the jukebox.

June 1988 :
 * At this point, there is still no ® on the show's logo.
 * The June 14 show is Episode #3,421, taped May 14.
 * Betty White makes a cameo on June 14.

July 1988 :
 * Jack Clark dies on July 21.
 * As of July 27, according to USA Today, there is still no permanent announcer.

August 1988 :
 * Johnny Gilbert fills in as announcer for one week this month, most likely the 1st.
 * Probably on August 8, and definitely by September 5, M.G. Kelly becomes the show's announcer. He began taping nighttime episodes shortly before August 17.

September 1988 :
 * By September 5, a "registered trademark" (®) symbol is added to the show's logo, just below the N.
 * Same Name debuts around September 6.
 * September 16 is believed to be the last appearance of the daytime Jackpot.

October 1988 :
 * On October 3, the Bonus Round rules are changed to give RSTLNE automatically and ask the contestant for three more consonants and a vowel; also, the time limit is reduced to 10 seconds. The first bonus puzzle under these rules is OREO COOKIES, which is not solved.
 * By mid-October, the Used Letter Board changes to a dry-erase board similar to those used in auditions since at least 1985. Other than being dry-erase, the new board retains the old formatting.
 * October 24 is Trick or Treat Week, held across all of NBC's daytime games. On Wheel, the turntable and spiral pillars are decorated for Halloween.
 * On October 26 (Jeannette/Lenna/Elizabeth), Rounds 1, 2, and the Bonus Round are Phrase.

November 1988 :
 * Wheel does not air on November 24 due to the Macy's Thanksgiving Day Parade.

December 1988 :

 * On December 30, Pat announces that he will be leaving the daytime show the following week.

1989
January 1989 :
 * Wheel does not air on January 2 due to the Tournament of Roses parade.
 * January 9 (Episode #3,564) is Pat's last daytime show, taped around October 1988. He steps down from daytime to host his short-lived talk show, The Pat Sajak Show, which debuts that night. On this day:
 * Appropriately, the Round 1 puzzle is TAKE GOOD CARE OF YOURSELF.
 * Following the Bonus Round, Pat makes out with Vanna until Merv walks up and taps Pat's shoulder.
 * No name is ever given for Pat's replacement, as no host had been chosen at the time of the episode's recording, although Pat and Merv's comments suggest otherwise.
 * Several comments during the show mention "Friday" and "Monday", suggesting an airdate of January 6. It appears that a recent NBC News special report (possibly the Pan-Am flight bombing in Lockerbie, Scotland on December 21) pre-empted Wheel at some point and pushed everything forward by a day.
 * January 9 is the last of only three daytime episodes to be aired by GSN, reran in 2007 as part of the marathon following Merv's death.
 * Rolf.jpgry 10 is Rolf Benirschke's first show, taped December 14, 1988. Promos aired on January 4-9 advertising his debut, "starting Tuesday". On this day:
 * The money graphic returns to being in the center of the screen
 * M.G.'s intro ends with "And now, here's your hostess: Vanna White!" Vanna walks out to the host's area, and introduces Rolf. The two converse during the first segment, which lasts just over two minutes, with the contestant interviews and Round 1 beginning in the second segment.
 * The post-game chat is not done near the Wheel.
 * On at least January 10-12, no credit is given for Rolf's wardrobe, although this is likely an error. In the case of the 10th, there is a blank spot between Vanna's credit and the beginning of the full credit roll.
 * On at least January 11 and 12, M.G.'s intro ends with "And now, here's your new host: Rolf Benirschke!"
 * Beginning on January 11, the consolation prize (only mentioned as being given to one contestant) is described after the last commercial break.
 * As of January 12, the money graphic still appears in the center of the screen.

February 1989 :
 * An episode between January 12 and the end of June has the first known instance of a contestant incorrectly solving a fully-revealed puzzle. The answer is SAINT THOMAS AQUINAS, which at least one player mispronounces.
 * On two episodes from the above timeframe, the game ends in a tie. On the first instance, likely in late January or early February, Rolf admits on-camera that he does not know what to do.
 * February 17 is M.G.'s last episode; Charlie returns on the 20th.
 * By February 22 (Lois/Cami/Rochelle), the money graphic returns to being at the top of the screen.
 * On February 22:
 * Lois gets three Free Spins in Round 1.
 * Rolf's Final Spin lands on Lose A Turn.
 * Lois sweeps the game and wins a Toyota Tercel in the Bonus Round.
 * As of February 22, Augustus still provides Rolf's wardrobe.
 * Before & After debuts around February 27.

March 1989 :
 * On March 24, Rolf and Vanna wish everyone at home a Happy Easter.
 * On March 27, Rolf and Vanna talk to Charlie at the end of the show.

April 1989 :
 * During a Teen Week around Spring, Rolf congratulates himself for hitting $2,000 on a Final Spin. The blue contestant, Jade, then points out that Rolf is looking at the blue arrow and has actually hit Bankrupt.

May 1989 :
 * The May 9 show is Episode #3,649.
 * On May 22, due to declining ratings and an inability to come to a license fee agreement with Merv (and despite Wheel having a three-year studio-use contract signed in 1987), NBC announces the show's cancellation and replacement by reruns of The Golden Girls.
 * On May 23, CBS announces the return of Wheel "beginning sometime this Summer". At this point, the Sacramento Bee notes, "the Rolf Benirschke fan club needn't panic – he will not be out of work even one day".

June 1989 :
 * Stephen Burrows, later a writer and director, is a contestant (as "Steve") on an episode taped June 10. On April 18, 1991, he releases the half-hour short The Soldier of Fortune about his "actual appearance and subsequent humiliation on [Wheel], where he is generally considered to be the worst contestant in the history of the show", which wins 29 film festivals.
 * While the short is known to contain clips of his episode, it is not known how the short is structured. Given the running time and the length of an episode minus commercials, it is possible that Soldier simply consists of his episode in full with the remaining time devoted to Burrows' comments and/or the aftermath.
 * According to the Internet Movie Database, Steve is the first player to buy all five vowels in succession and still not solve the puzzle.
 * June 30 (Julie/Jay/Marc) is Rolf's last episode, the last with the shopping format, the last taped in Studio 4 at NBC Studios in Burbank, and the last use of $2,000 as a cash value. On this day:
 * Rolf's Final Spin lands on Bankrupt.
 * Rolf and Vanna talk about Summer after the game, with Rolf mentioning that he will be going to the beach.
 * The credit roll is of the extended style (Music, Utility, Flyman, etc.) like those used on other NBC finales.
 * Charlie says his name while signing off, the second known instance of a daytime announcer doing so.
 * By the end of June, a contestant wins $65,271, the largest of the daytime run.
 * By June 30, the money graphic returns to the center of the screen.
 * By June 30, Rick Pallack begins providing the host's wardrobe.

July 1989 :
 * In early July (definitely before the 7th), TV Guide runs an ad promoting the show's move to CBS. No host is named, although a blurb of "New Host" confirms Rolf's dismissal.
 * On July 7, Bob Goen is announced as the new host.
 * July 17 is the CBS premiere, taped on the 14th, and Bob and Vanna appear on that day's CBS This Morning to promote the debut. Wheel moves back to 10:30 AM, replacing the Chuck Henry version of Now You See It, and nearly every element changes in some way:
 * 1) The show moves to CBS Television City's Studio 33 (now the Bob Barker Studio), the same studio in which The Price Is Right has taped since 1972.
 * 2) The original episode tally, in place since 1975, is discarded in favor of a three-digit counter prefaced by "#C".
 * 3) The shopping format is retired, replaced by a scaled-down version of the nighttime play-for-cash format. The shopping cue "Nightwalk" is sporadically used as a prize cue.
 * 4) The "wrong letter" buzzer, Bankrupt slide whistle, "only vowels remain" beeps, Final Spin bells, and category chimes are all changed to the current ones; the "wrong letter" buzzer was previously heard on Bumper Stumpers. A new "time's up" buzzer consisting of two short buzzes is added to the Bonus Round, where previously the elongated "wrong letter" buzzer was used. The Bonus Round timer beeps are also changed to a style that remains on nighttime until 1999. In addition, the CBS applause machine used on their other game shows carries over.
 * 5) "Changing Keys" and the puzzle-solve cue are rearranged to have the melody on saxophone and jazz guitar, backed by organ and percussion. This and all subsequent versions of "Changing Keys" end on a single note instead of the puzzle-solve cue. The bridge of "Changing Keys" continues to play when Vanna is introduced.
 * 6) The turntable is heavily redone, with only a few prizes and other decorations now present on it. It likely rotates to show various prizes, but it is not known to have done so on-camera. Also, at least one spiral pillar is retained, placed to the left and back of the contestant area.
 * 7) The host's area and Bonus Round area each now have a backdrop of silver chevrons, while the host's area and the spaces between the players' score displays are changed to a solid brown design.
 * 8) The sunburst contestant backdrops are upgraded to chevrons that continue to show total champion winnings with the same limitations. As shopping is no longer part of the format, the "ON ACCOUNT" display is now obscured.
 * 9) The contestant nametags are now parallelogram-shaped, with a gray background, although the letters are still white. 1stbob4.jpgWof01PrizeBy1250.jpg
 * 10) The Wheel offers less than half of what it did previously, and while the show has a four-round minimum the layouts are a variant of the three-round structure: $500 returns to being the top value for Round 1 and remains for Round 2, followed by $1,000 in Round 3 and $1,250 thereafter. For the first time since 1975, $50 and $75 appear on the Wheel.
 * 11) Prize wedges are reintroduced to daytime, with a new prize added each time a previous one is claimed (up to two new prizes per round). If two Prizes are put on the Wheel at once, their wedges are not shown in close-up. The distribution presents the possibility of having three prizes on the Wheel by Round 4.
 * 12) The Free Spin tokens become green, with "SPIN" in the center and "Free" on the top and bottom in yellow script.
 * 13) As a result of the reduced Wheel values, vowels now cost $200.
 * 14) The Bonus Round now offers subcompact cars, a cash prize of $5,000, and other prizes generally valued at less than $10,000; the $5,000 is displayed on a green disc suspended from the ceiling, which rotates counterclockwise, and its font (save for the dollar sign) is Clarendon-like and similar to its nighttime front game counterpart. While nighttime changes Bonus Round prize selection to a random draw from the W-H-E-E-L envelopes on September 4, daytime allows contestants to pick their bonus prize until the end (although picking the cash is not as common). $5,000_Sign.jpg
 * 15) If the $5,000 is played for, the sign lowers and Charlie announces one of several rotating lines related to it.
 * 16) The opening remains about the same as Rolf's last show, with a "CBS StereoSound Where Available" graphic added. Charlie's intro is now "Look at this studio, filled with lots of exciting prizes! Including a new $5,000 cash bonus, this sporty little compact car, and a wonderfully romantic Caribbean cruise, plus thousands of dollars in cash, all waiting to be won on today's show! Yes, from Television City in Hollywood, it's Wheel of Fortune! And now, here's your host: Bob Goen!"
 * 17) As Charlie says "plus thousands of dollars in cash", the money graphic appears at the bottom of the screen; oddly, during the week of July 17, it alternates between $41,000 (Monday, Tuesday, and Friday) and $42,000 (Wednesday and Thursday).
 * 18) As Charlie says "waiting to be won", a graphic of the Wheel forms, starting with several colored rings curling into place to form the frame of the Wheel, followed by the wedges falling down to form the Wheel itself (albeit extremely inaccurate, lacking Bankrupt and Lose A Turn while including values such as $850 {not used since 1979}, an "off-model" yellow $750, and the nonexistent {outside of rug and turntable layouts} $950). Once the Wheel graphic is fully formed, it tilts to form the "O" in "OF", with the rest of the show's name spelled out in gold letters. It then fades away as Charlie introduces Bob.
 * 19) The overhead Wheel shot during the close is now zoomed in on the center; only the bottoms of the wedges are visible, including the "50" in $1,250 as well as any remaining Prize wedges.
 * 20) Per CBS game show tradition, the sponsor list becomes two separate ones: "The following suppliers of products have paid for their use & promotion." and "The following suppliers of products or services have furnished them free or at less than retail."
 * 21) The credits end with "Recorded at CBS Television City in Hollywood, California", with the CBS Eye logo included in the disclaimer. If there is a short credit roll, it is shown as a chyron; but if there is a full credit roll, it scrolls up.
 * On July 17 (Fay/Rick/Lou):
 * After Bob's entrance, he mentions that "It is great to be here at our new home at CBS. Although some things may change, some things always stay the same, thank goodness for that." He then introduces Vanna.
 * Inexplicably, the winner of Rolf's last episode does not return.
 * The "only vowels remain" beeps sound more muted than they would later be, although this could be due to the quality of the video.
 * Person/Fictional Character debuts in Round 3.
 * Lou buys a repeated E in Round 3, but it is not acknowledged as such until Vanna accidentally walks to the trilon where the E has already been revealed.
 * Pat appears before Round 4 to wish Bob and the players good luck; at the same time, Bob quips about succeeding Pat on the nighttime show.
 * The first Wheel Prize appears in Round 2: a $916 trip to Lake Tahoe. It is not claimed, and is replaced by two prizes in Round 3. One of these is won and replaced in Round 4 by a fourth prize.
 * During the post-game chat, Vanna and Bob mention the switch to play-for-cash and hold up two of the new Free Spin discs.
 * As it no longer applies, "Gift certificates do not include sales tax." is removed from Charlie's closing disclaimer.
 * On July 17 or 18, The Pat Sajak Show features a segment about the daytime Wheel, with Pat walking downstairs to Studio 33 and surprising Bob, Vanna, and Charlie. As $1,250 is present on the Wheel, along with a Prize wedge ending in "-ng", Pat's appearance was likely before Round 4. The segment also explains the puzzle board and Used Letter Board, and has the only known shot of the $5,000 sign's reverse.
 * On July 18:
 * Charlie's intro changes slightly: the prize descriptions are now "Including our all-new $5,000 cash bonus, a gorgeous handwoven oriental rug, and a fabulous sapphire and diamond ring, plus thousands of dollars in cash..." Two-Digit_Values_with_Diamonds.jpg
 * The two-digit values are given diamonds, and the tan $50 near Bankrupt is increased to a yellow $300. This yellow $300 wedge is the same "off-model" variant (with a larger dollar sign and smaller 3) used at this point to cover Free Spin in later nighttime rounds.
 * Same Name (Round 2) uses an ampersand for the first time, instead of spelling out AND. The answer is EVE & ELIZABETH ARDEN.
 * Two prizes are introduced in Round 4, as the Round 2 prize is lost to Bankrupt (however, Bob does not take away the wedge) and the Round 3 prize won. One of the Round 4 prizes is also won, and its wedge strangely remains on that player's arrow for the rest of the show.
 * As the show goes to break after Round 4, the camera cuts from the contestant area to a small zoom-in on the $5,000 sign.
 * Charlie's "the prices of the prizes" closing disclaimer is removed entirely. In its place on this episode, he states that "This program has been edited for broadcast."
 * On July 19:
 * Charlie's intro changes again: "lots of exciting prizes" is changed to "wonderful and exciting prizes", and the next few episodes have different prize descriptions.
 * July 19: "Including $5,000 in very spendable cash, this nifty little compact car, lovely pearl jewelry, plus thousands of dollars in cash..." (Oddly, the "new" intro animation starts while the rings are forming.)
 * July 20: "Including a great $5,000 cash bonus, a glamorous cruise through the Caribbean, and for entertaining, a contemporary bar with accessories, plus thousands of dollars in cash..."
 * July 21: "Including a romantic seven-day Caribbean cruise, a beautiful Oriental rug, and a $9,000 sapphire and diamond ring, plus thousands of dollars in cash..."
 * The contestant nametag letters become black, likely because the white lettering was difficult to read.
 * The Rounds 1-2 Wheel layout undergoes several value changes: the "off-model" $300 is replaced by $50♦ and swaps positions with the $125 next to it, the pink $50♦ between Bankrupt and Free Spin increases to $175, the purple $50♦ nearby increases to $300, and the blue $75♦ between Free Spin and Lose A Turn increases to $200.
 * Round 1 has the first instance of a puzzle using zeroes instead of O's, an anomaly which appears on some puzzles and spreads to nighttime on September 7. The zeroes, likely recycled from the "3,000th show" promotional shot, can be discerned as being much wider and rounder than the regular O's. As far as is known, puzzles only either used O's or zeroes, but never both.
 * After the Round 2 prize is claimed but not won, two new prizes are introduced in Round 3. One of those is won, and is replaced by another prize in Round 4.
 * During the post-game chat, Bob and Vanna talk about more differences from the nighttime show, including the reduction of vowel cost to $200. Bob quips that they "made it through the show without Sajak having to come in and bother us".
 * On July 20:
 * For the first time, there are three Prize wedges on the Wheel in Round 4. They are neither claimed nor won. One of them is the aforementioned bar in Charlie's intro, worth $2,976. It starts out on the red $200 next to $1,250 in Round 4 and moves to the pink $300 next to Bankrupt in Round 5.
 * In Round 4, the category chyron disappears a second into the first spin, but reappears after that spin is complete.
 * Contestant Patrick retires, the first of the Goen era, with $19,230.
 * Before coming back from the final break, CBS airs a promo for the show.
 * The post-game chat is not done near the Wheel.
 * On July 21:
 * The lights on the $5,000 sign are off during the entire show, except during the Bonus Round when the champion decides to play for the cash.
 * Round 2 is a Same Name of EGG & VANNA WHITE.
 * Round 3 has zeroes for O's.
 * There are only two prizes available during Rounds 2 and 3 combined, and one of them is won in Round 3.
 * Round 4 begins as a Speed-Up, with the Art wedge still on the Wheel. Unusually, the chimes sound as the category is revealed.
 * The taping Pat appeared at on The Pat Sajak Show airs sometime between July 24 and August 11.
 * On an episode sometime during Goen's tenure, there is believed to be an episode which goes to seven rounds; interestingly, this is due to a tiebreaker being done after Round 6.
 * On another episode during Goen's tenure, Vanna does the Final Spin for the only known time, doing so at Bob's request after he repeatedly lands on Bankrupt.

August 1989 :
 * As of August 4, Wheel draws a 2.8 on the Nielsen ratings system with a 12 share, only slightly higher than the average of Now You See It.
 * By August 22 (Marleen/Mary Ellen/Lee):
 * The NBC opening shot and money graphic are dropped. The opening is changed to an angled shot of the contestant area with the $5,000 sign at left, with the players running onstage during the "Wheel! Of! Fortune!" chant. The theme is slightly updated with a new opening version which begins with a similar crescendo to "Give It One", and the version previously used there continues to be used during the credits. The camera pans from the Wheel to the board as the "new" logo, now the regular one, appears; cuts to the audience as the animation is reversed; then cuts again to center stage while Charlie introduces Bob.
 * Charlie's opening spiel is changed to "From Television City in Hollywood, one of America's most loved shows! The famous Wheel is spinning your way with lots of cash and an assortment of sumptuous prizes! And now, here's your host: Bob Goen!"
 * The purple $50♦ in Rounds 1-2 is increased to $300, leaving just one each of $50♦ and $75♦ on the Wheel.
 * The $5,000 sign now rotates during the opening and credits, as well as when the cash is played for. Previously, the sign did not rotate during the credits.
 * On August 22:
 * The Round 2 prize is claimed in Round 3, but not won; it is replaced by another prize in Round 4, which is claimed and won. The Round 3 prize is not claimed and is removed in Round 6, which begins with the Final Spin.
 * For the first known time in the Goen era, the Bonus Round is played for something other than the cash or a car: specifically, an East Coast tour.
 * The closing plugs begin immediately after the final commercial break.
 * On August 24 (Rose/Jim/Martha Ann):
 * After the Round 2 prize is claimed, two new prizes are introduced in Round 3 and one in Round 4, again resulting in three prizes on the Wheel for Round 4.
 * Round 3 is the first known appearance of Person/Title. The puzzle uses zeroes for O's.
 * There is also a contestant plug before the fee plugs.
 * The theme music runs to the end, just after the Enterprises logo appears.
 * By August 24, Fred Hayman of Beverly Hills begins providing Vanna's wardrobe.
 * As of August 24, Rick Pallack still provides Bob's wardrobe.

September 1989 :
 * On September 4 or 11, the puzzle board's chase lights begin to be used during the opening; previously, they were static.
 * On September 18 (Dave/Sandra/Ric):
 * The category chyrons are red, possibly a random choice due to Vanna's dress (a flowery print).
 * Several times during the show, Bob forgets to ask Ric if he wants to use his Free Spin.
 * There are two sets of repeated categories: Same Name in Rounds 1 and 5, Phrase in Rounds 2 and 4.
 * By September 18, the Rounds 1-2 minimum returns to $100: the pink $50♦ is increased to $250, the blue $75♦ is increased to $400, and the purple $300 near Bankrupt is dropped to $100.
 * As of September 18, the set still looks the same as it did on July 17.
 * By the end of this month, puzzles no longer use zeroes for O's.

October 1989 :
 * Beginning on October 2, the dollar sign disappears from the contestant score displays if that player has at least $10,000, an apparent glitch which remains until the displays are redone around August 1990.
 * On October 16:
 * The Free Spin wedge becomes a single Free Spin token placed on various amounts, with the spot formerly holding the wedge becoming $400. This is the last change to the Rounds 1-2 layout, the only one to be altered since the CBS debut three months earlier.
 * Person/Fictional Character is renamed Star & Role.
 * The winner's Bonus Round letter choices begin to be displayed in black, a color typically not used by the category chyrons.

November 1989 :
 * Wheel does not air on November 23 due to the All-American Thanksgiving Day Parade.
 * Husband & Wife debuts around November 27.

December 1989 :
 * Family debuts around December 25.
 * The December 27 show is Episode #C115.

1990
January 1990 :
 * Wheel does not air on January 1 due to the Tournament of Roses parade.
 * Sometime this year, CBS airs a promo of Bob in the show's office, using his last name in several puns. The nighttime 1987 Round 1 template is used as a wiping graphic (similar to one of the nighttime Disney World intros) and in the background on a physical prop.
 * By January 4, cars begin to be displayed on the turntables from the nighttime show. If a champion wins a car and the post-game chat and credits take place there (instead of near the Wheel), the turntables are not active.
 * As of January 4, vowels still cost $200.
 * January 4 is the last time Nancy Jones is listed first on full credit rolls. Beginning the following week, Merv's credit of Executive Producer is added to the list, above Nancy.
 * As of the above credit change, Kelly Haus is still listed under Production Staff.

February 1990 :
 * As of February 22, Renee Hoss is still credited under that name during full credit rolls.
 * By February 22, Kelly Haus is dismissed for unknown reasons.

March 1990 :
 * By March 5, the show holds a Soap Stars Week with cast members from The Young and the Restless (Jess Walton/Doug Davidson/Lauralee Bell), The Bold and the Beautiful (Daniel McVicar/Lauren Koslow/John McCook), Guiding Light (Kimberley Simms/James Goodwin/Jay Hammer), and As the World Turns (Michael Swan/Margaret Reed/Gregory Beecroft). Based on this and a print ad, it likely used the Friday Finals format with each soap getting its own episode.
 * An article from March 7 notes that Hammer donated his winnings to his alma mater: the University of the Pacific in Stockton, California.
 * While all twelve were on their respective shows before July 1989, it is known that Reed, Beecroft, and Goodwin leave their respective shows in 1990 (Beecroft around February, Goodwin on May 14, and Reed at an unknown point).
 * By March 14, Renee Hoss begins to be credited as "Renee Hoss-Johnson" in the full credit roll.
 * Sometime between March 14 and 30, Shannon Williams is promoted from Production Staff to Prize Coordinator, replacing Steve Davis.
 * Assuming that the daytime show offered fur coats after the move to CBS, they are dropped from the prize rotation late this month at the insistence of PETA.

April 1990 :

May 1990 :

June 1990 :

July 1990 :
 * July 2 is Armed Forces Week, where contestants are called from the audience to play (the first three by Bob, all subsequent names by Vanna) from a fishbowl sitting on the host's railing.
 * Several gameplay elements are slightly altered for this week:
 * The players do not draw numbers to determine position, instead taking the spots from left to right in the order they were called. After each round, the two players who do not solve the puzzle are eliminated, and two new contestants are called to replace them; if one new player wins and the other does not get a turn, s/he is not eliminated and only one new contestant is called.
 * $500 is the top value in Round 1, $1,000 in Round 2, and $1,250 in Rounds 3+. In relation to this, the first Wheel Prize is added before Round 1, a practice that becomes the norm when Wheel returns to NBC in January.
 * Rounds 2+ begin with the "next" position from the one that won the previous round (i.e., if the yellow player wins Round 1 then the blue player begins Round 2, etc.).
 * The player with the most winnings (not necessarily the winner of the final round) plays the Bonus Round.
 * Some other notes about this week:
 * After the logo flies into place, an American flag graphic wipes by from left to right during Charlie's opening spiel, replacing the second half of the logo animation.
 * The set is decorated for this week: an American flag is present behind the host's area, a large Armed Forces emblem is attached to the top-center of the puzzle board, and various Armed Forces-related symbols and flags are placed around the audience area.
 * By July 5, the cost of buying a vowel is reduced to $100.
 * On July 5:
 * The first Wheel Prize is a $500 necklace. This is very likely the least expensive Wheel prize ever offered on the daytime show, and known to be one of the least expensive Wheel prizes overall.
 * As the signoffs and credits take place near the car won by the day's champion, the car turntable is not active.
 * Around this point (known to not be July 5 or 23), a contestant solves NICK NOLTE STARRING IN Q&A with only one letter (most likely the N's) revealed.
 * On July 23 (Rochelle/Tammy/Hury):
 * Three females play.
 * The Round 1 puzzle HALLELUJAH is an extremely rare instance of both a one-word Phrase and a main-game puzzle with only three unique consonants. 10 wrong letters are called in this round, including the first five turns, and no vowels are bought.
 * During the final segment, Bob mentions that a staff member named Karen is leaving at the end of this week. The staffer in question is shown briefly, but the only Karen listed in the full credit roll is Karen Griffith, who did not leave the show and became co-producer in Season 14; this would suggest that she only left daytime, and then only for a brief period, as she is listed in the full credit roll of January 11, 1991.
 * For the first known time, Augustus provides Bob's wardrobe.
 * A crane shot of the $5,000 sign is used during the credits.
 * As of July 23, the contestant area still looks the same as it did on July 17, 1989.

August 1990 :

September 1990 :
 * By September 3:
 * 1) The score displays are extended to allow for seven digits, with the dollar sign now "adjusting" to the scores instead of remaining at the far left. The new displays are also connected to each other, removing the solid brown space that was previously there.
 * 2) The lights surrounding the Wheel become much brighter. The bottom layer of lights, which previously flashed counterclockwise, now flash clockwise as the Wheel is spinning (much like the other layers).
 * 3) The Wheel is noticeably tighter and louder.
 * 4) Following the last puzzle of the game, the cumulative total of an outgoing or returning champion is shown flashing in a similar manner to the post-Bonus Round totals.
 * Possibly on September 3, and definitely by December 25, the chevron contestant backdrops become darker.
 * As of September 11, the original rules for picking up Prize wedges and the Free Spin are still in use (picking them up automatically and calling a letter for the value underneath).

October 1990 :
 * Clue debuts around this point, with the bonus worth $250.

November 1990 :
 * A Chicago Tribune article from March 17, 1991 mentions a play-by-phone contest being held for 21 days this month. The article notes that "a record 4.7 million people played, as well as watched, Wheel of Fortune in a one-shot promotion".
 * Episode #4,000 likely airs around November 7.
 * For the last time, Wheel does not air on November 22 due to the All-American Thanksgiving Day Parade.

December 1990 :
 * By December 25, the rules for picking up Prizes and the Free Spin are altered to require a correct letter call before picking up the wedge/token.
 * December 25 is Christmas-themed, with a decorated set: lights that flash at the open and close, miniature golden bows on the puzzle board, and a large golden bow on the $9,995 Geo Metro onstage. Also, the chyrons are displayed in red and green for the holidays. On this episode:
 * After his entrance, Bob wishes the viewers a Merry Christmas and tells them that if they aren't spending the day with their own family, to let him, Charlie, Vanna, and the contestants be the "surrogate family" for the day.
 * After the Bonus Round, Vanna gives Bob a piece of crochet with his last name inscribed in capital letters.
 * After the CBS Television City chyron is shown, the Enterprises logo is revealed via a trilon effect just as Charlie's spiel begins.

1991
January 1991 :
 * For the last time, Wheel does not air on January 1 due to the Tournament of Roses parade.
 * January 11 (Brenna/Jim/Sonja) is the last CBS episode. On this day:
 * After Bob enters, he notices the audience doing the Wave. He laughs and mentions this, afterward quipping that "I feel like Pedro Guerrero all of a sudden."
 * Rounds 3 and 5 are Before & After.
 * In Round 5, Jim tries to buy a vowel after claiming a Prize wedge, but Bob stops him as he has no money. He loses the Prize to Bankrupt on the next turn.
 * Afterward, the Speed-Up bells sound just as Sonja begins to spin. She is allowed to complete her turn, after which the bells sound again and Bob does the Final Spin.
 * The bonus puzzle KING OF THE ROAD uses three lines of the puzzle board, a practice almost entirely abandoned after mid-1989.
 * Bob and Vanna only have time to sign off.
 * For the last time, the credits include "Recorded at CBS Television City in Hollywood, California".
 * After the credits finish scrolling, the picture zooms back to reveal a gray background, at which point it flips over to reveal the Merv Griffin Enterprises logo just as Charlie's spiel begins.
 * On January 14, the show moves back to NBC's daytime schedule, replacing Let's Make A Deal, but continues to tape at Television City. Unlike the move to CBS, the January 11 winner is held over. The return to NBC results in several changes:
 * 1) The CBS episode tally is discarded in favor of a new three-digit counter prefaced by "#DT".
 * 2) Charlie's intro is changed to "From Hollywood, the famous Wheel is spinning, spinning, spinning, and the players will be winning, winning, winning! Because there's lots of cash and some fabulous prizes just waiting to be won on Wheel of Fortune! With our host, Bob Goen, and our hostess, Vanna White!" Bob gives a short greeting after Charlie says his name. DaytimeLogo1-14-91.png
 * 3) The opening is slightly altered to superimpose the logo over a shot of the day's contestants. The logo itself settles to the bottom of the screen when it finishes forming, and rises back up to zoom back out.
 * 4) The first prize is now added in Round 1, so the three-prize scenario could occur in Round 3.
 * 5) If a prize is claimed, its value now appears on a chyron.
 * 6) Except for the cash, Bonus Round prizes are increased to the $10,000 range.
 * 7) The fee plugs are either eliminated or moved to after the third segment. The only end-of-show plug that continues is promotion of Wheel merchandise (all based on the nighttime show). As the credits begin, the Wheel can be seen slowly starting its automation. During any sweepstakes episodes (see below), the credits begin with a disclaimer about the sweepstakes (phone number, mail-in address, and addresses for both rules and winner's lists) followed by either an aforementioned merchandise plug or the credits.
 * 8) If a fee plug occurs after the third segment, the graphic flips up for the camera at the beginning and then flips over at the end (similar to a book page) to a shot of the audience; during this shot, a stacked non-logo puzzle board-style "Wheel of Fortune" text on a rolling Rounds 1-2 template with Free Spin disc and Prize wedge (also seen on some nighttime Walt Disney World shows) scrolls across the bottom of the screen.
 * 9) The sponsor list is back as one, and, as per NBC's game show tradition, the disclaimer is changed to "The following companies have paid a fee and/or furnished merchandise to the production company for promoting their products."
 * On January 14:
 * Bob notes that he and the staff are "pleased as punch to be back home on NBC".
 * In a fairly unusual occurrence, the Prize wedges remaining on the Wheel are removed before Round 5 so Bob can make the Final Spin.
 * After the closing plug (for Pressman's second Travel Edition), the sponsor list is shown as the camera zooms out from the center of the spinning Wheel, almost to the point where it can be seen in its entirety (a shot very similar to the classic host and hostess sign-off in the 1970s-80s).
 * Sometime after the return to NBC, GUM is a bonus puzzle. This is both the first known instance of a three-letter bonus puzzle and a bonus puzzle without RSTLNE in it.
 * On an episode sometime between January 16 and early February (Edward/Diana/Patrick), Patrick calls a letter on a Prize wedge and asks to solve immediately afterward. Bob reminds him to pick up the Prize wedge, which Patrick does, after which he solves the puzzle.
 * By the above episode, the prize value chyron begins flashing if a contestant claims it.

February 1991 :
 * February 25-March 25 is the Cashpot Sweepstakes, where home viewers enter to solve each day's Cashpot puzzle: a partially-filled puzzle is shown after Round 1 with category as the Bonus Round timer plays, followed by the double-buzz; viewers then have until 10:00 AM Eastern the following day to call 900-436-5000 ($2.00 per minute, average call 2 minutes) to solve the puzzle, using their touch-tone phone keys to fill in the letters; viewers may enter twice per puzzle, but busy signals do not count toward this. Some other notes about the Sweepstakes:
 * There is a no-cost mail-in alternate method of entering, which is to send a self-addressed stamped envelope to: Wheel's "Cash Pot" Alternate Entry Control; P.O. Box 34985; Omaha, Nebraska; 68134. Envelopes must be received by April 10 for alternate entry calls on April 19.
 * Viewers requesting a list of rules and/or winners may send a self-addressed stamped envelope to: "Rules" and/or "Winners": Wheel's Cash Pot; P.O. Box 662; Sayreville, New Jersey; 08871.
 * For the first three weeks, five winners each day receive $1,000 in cash, for a total of $25,000 each week.
 * The $1,000 awards and $25,000 total are signified by the "classic" money graphics that had been dropped from daytime in July or August 1989.
 * The deadline for Friday puzzles is 10:00 AM the following Monday.
 * All callers receive a booklet containing over $5 in discount coupons on six well-known products from the Thomas J. Lipton company; Charlie plugs one of these products after Bob mentions this. Vermont and Washington State residents may omit return postage. Viewers must allow 6-8 weeks for the Thomas J. Lipton product coupons to be mailed.
 * Proceeds from the calls will be donated by NBC to a charity of their choice.
 * Only one round is played in the first segment, and it is believed that some games only go to three rounds.
 * Upon coming back from the final break, Charlie gives the answer to the previous episode's Cashpot puzzle. The puzzle board's trilons are all showing their green-glitter side; the set is quiet and only Bob is present, reminding viewers about the sweepstakes before he signs off.
 * The February 26 show is Episode #DT032.

March 1991 :
 * The known Cashpot puzzles this month are:
 * March 8: HIGH AND MIGHTY (or HIGH & MIGHTY).
 * March 11: PEP TALK.
 * March 15 (possibly): I Q TEST; a Chicago Tribune picture dated March 17 has this puzzle with the Cashpot phone number and cost.
 * March 18: CHEESE PIZZA.
 * March 19: NO TRESPASSING.
 * March 20: RED AS A BEET.
 * March 21: PINCH HITTER.
 * By March 11 (Jennifer/Trei/Whitney), the opening is slightly altered to remove the superimposed Wheel logo from the shot of the day's contestants.
 * For the week of March 18 (the final Cashpot week), the number of winners per day is doubled to 10; as a result, the total cash payout is doubled to $50,000 (also signified by the aforementioned money graphic). This is the last known use of the "large" (five- or six-digit) money graphics on the daytime show.
 * On March 19 (John/Glenn/Elaine):
 * The Prize wedges move between rounds: Round 1's prize (artwork) starts on the pink $250, then moves to the yellow $200 for Rounds 2-3; Round 2's prize (a ring) starts on the purple $100 and moves to the blue $100 for Round 3, with that round's prize (a spa) taking the purple $100.
 * For only the second known time, Augustus provides Bob's wardrobe.
 * On March 21 (Rosie/Dave/Mary):
 * Bob still does the opening spin.
 * After the March 20 Cashpot answer is announced, Vanna is next to Bob on-set as they chat about the 21st being the first day of Spring and how the proverb "March comes in like a lion and out like a lamb." came about. Bob then reads off some of the sweepstakes winners and reminds the viewers about the day's puzzle before he and Vanna sign off.
 * For the third known time, Augustus provides Bob's wardrobe.
 * On March 25, the final Cashpot puzzle answer and its winners are announced. PhoneWheel1991.png
 * Possibly after the Cashpot Sweepstakes, the show holds a Phone Wheel of Fortune game through March 31. Viewers call in anytime during the week and play a game over the phone much like the Cashpot, by calling 900-454-8101 and trying to solve five puzzles in the fastest time. Winners receive $500 in cash, with all callers receiving a Super Family Savings Book containing more than $500 in discount coupons. Unlike the Cashpot, the cost is $1.95 per minute and the average call is 5 minutes.
 * At least one commercial is done for this contest, which results in the final time the "Wheel! Of! Fortune!" chant is used with an overhead shot of the spinning Wheel (in this case, the Round 1 layout with no Free Spin and no logo covering the Wheel), and possibly the last use of the shot itself. The camera zooms into the green center as the Phone Wheel of Fortune logo appears, similar to the opening transition used from the 1974 pilots through at least November 3, 1975.

April 1991 :
 * As of April 16, the Bonus Round chevron backdrops still look the same as they did on July 17, 1989.

May 1991 :
 * According to a contemporary magazine article, the show does another play-by-phone contest this month.
 * By May 14, the Bonus Round chevron backdrops add lights which flash during the opening, bonus prize descriptions, and credits. Probably at this point, and definitely by the 23rd, Bob stops doing the opening spin entirely.
 * On May 23 (Sherrie/Joyce/Suanne):
 * Only Thing(s) and Phrase are used: Round 1 and the Bonus Round are Thing, Round 4 is Things, and Rounds 2-3 are Phrase.
 * There are three Prizes on the Wheel in Round 3; one is claimed, and is replaced by a fourth Prize in Round 4.
 * The cameras switch to the over-the-Wheel shot too soon, catching it in mid-spin.
 * During the closing disclaimer, the day's champion can be seen walking in to join Bob and Vanna.
 * On May 24, all Prize wedges are removed before Round 5, which begins as a Speed-Up.
 * On May 24 and 27, Bob plugs the Summer Vacation Bonanza Sweepstakes (see below). The latter is the last known use of the "classic" money graphic, which interestingly has a large shadow effect.
 * May 27 is Memorial Day. On this episode:
 * In honor of the holiday, Vanna wears Stars and Stripes clothing.
 * The remaining Prize wedges are not removed before the Final Spin, but are absent from the Wheel during the credits.
 * There is a rare instance of a four-line puzzle in the Speed-Up round.
 * The contestant's Bonus Round letters are displayed in light green. This is either a fluke or a short-lived alteration; see below.
 * For the fourth known time, Augustus provides Bob's wardrobe.

June 1991 :
 * June 3-July 1 is the Summer Vacation Bonanza Sweepstakes, played much like the Cashpot and Phone Wheel of Fortune. Like the Cashpot, average calls are 2 minutes and cost $2.00 per minute, and the game is played the same way (see rules, above). Each puzzle awards a vacation and five $1,000 cash prizes, with destinations including the Bahamas, Hawaii, Mexico, and Walt Disney World (Orlando, Florida); each vacation includes airfare and $500 spending cash. Some other notes about the Sweepstakes:
 * All callers receive Summer Bonanza coupons, with discounts for various hotels.
 * The phone number is changed to 900-436-4000. The address for rules and/or winners is changed to "Rules" and/or "Winners": Wheel's Summer Vacation Bonanza; P.O. Box 678; Sayreville, New Jersey, 08871.
 * On a Friday episode sometime this month, possibly the 28th (Gitta/Cheyenne/Ed), the contestant's Bonus Round letters appear to be displayed in black.

July 1991 :
 * Alternate entry request envelopes for the above sweepstakes are accepted through July 8; the week of July 15 is used for alternate entry calls.
 * It is possible, but by no means certain, that some changes made for Seasons 8-9 are implemented in July or August.

August 1991 :
 * August 5 is Teen Week, with the Friday Finals format.
 * On August 9 (Staci/Shawn/Sharon):
 * The Bonus Round chevron backdrops are not present. It is not known whether this was a permanent change.
 * Bob mentions that the finalists each won a car in their respective Bonus Round.
 * The Round 1 prize is a $1,000 Service Merchandise gift certificate for sporting goods, whose wedge says "SHOP". It is claimed and won.
 * The remaining Prize wedges are removed for the Final Spin.
 * Shawn wins $11,802 in the main game.
 * Shawn's letters (displayed in black) fill in the bonus puzzle SNACK BAR completely. He leaves with a grand total of $30,910, including the $5,000 from this Bonus Round.
 * Before the credits, the Wheel can be heard slowly starting its automation; towards the end, there is a wide shot of the set.
 * August 30 is the last first-run episode, although according to one recollection it is not mentioned on-air. Repeats continue through September 20.
 * By the end of August, Title/Author is almost certainly used at least once.
 * By the end of August, a contestant wins around $40,000-$50,000, the largest of the Goen era.
 * It was once rumored that Wheel continued through December 31, 1993 in first-run or repeats. While there have been cases of affiliates showing repeats of cancelled network games (the original versions of Jeopardy! and Gambit), the rumors about Wheel appear to be no more than wishful thinking.

Wheel 2000 (1997-98)

 * While Wheel 2000 aired in daytime on network television (more specifically, Saturday mornings on CBS), it is considered a derivative of the nighttime show. See Wheel 2000.
