Wheel of Fortune timeline (network)

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

(Due to NBC's practice at the time, many episodes from 1975-80 were destroyed or recorded over. Further, Game Show Network {henceforth referred to as GSN} has only shown three daytime episodes {not including Wheel 2000}. As a result, this timeline will be much less detailed than the nighttime one.)

Pilots (1973-74)
September 1973 :
 * At some point in September, the Shopper's Bazaar pilot is taped for NBC by request of Lin Bolen to Merv Griffin. It is markedly different from the eventual series in various ways, including:
 * 1) The show is hosted by Chuck Woolery, with announcer Mike Lawrence.
 * 2) The Wheel, designed by Ed Flesh, is vertical and mechanical with no Bankrupts, four Lose A Turn spaces, and one each of Free Spin and Buy A Vowel; the Wheel is halted by Chuck pressing a button once the player in control yells "Stop the Wheel!", although the Wheel occasionally resumes spinning almost immediately afterward. Unique spaces on this Wheel are $0, Free Vowel, and Your Own Clue; top dollar is $500 for Rounds 1-2 and $1,000 thereafter.
 * 3) Only three categories are used: Person, Place, and Thing, although they are not disclosed at the outset of each puzzle.
 * 4) The puzzle board is brown, with three rows and letters revealed by pull-cards; a fourth row acts as a Used Letter Board.
 * 5) Prizes and contestant winnings are handled by an "Accounting Department", an offstage board of three columns with four squares each which lists the four prizes each contestant had picked before the show and their values; below these cards are displays showing how much that player has earned toward winning it. While all three players' money carries over from round to round, a contestant can only "bank" the money if she solves a puzzle; should she do so and have enough to buy a prize on her list, she wins it (marked by the Accounting Department with a star placed next to that prize) and the remaining money is applied to the next prize.
 * 6) The Bonus Round, called the "Shopper's Special", is the name of the prize the contestant is playing for. The winner is shown all vowels in the puzzle, then has 30 seconds to give consonants to fill in the solution.
 * This pilot is held by GSN. Despite showing numerous pilots over the years, the network has not yet aired Shopper's Bazaar.
 * Shopper's Bazaar was mentioned in a $32,000 question on an episode of Who Wants To Be A Millionaire? (April 28, 2004), which asked what it was the original title of.

August 1974 :
 * On August 28, the second and third pilots (now called Wheel of Fortune) are taped in Los Angeles for NBC. Changes include:
 * 1) Edd Byrnes and Charlie O'Donnell replace Woolery and Lawrence.
 * 2) The show's theme song is changed to "Give It One" by Maynard Ferguson. It is not known what music was used on the Shopper's Bazaar pilot.
 * 3) The Wheel is redesigned by Flesh to be horizontal, with much larger wedges. Bankrupt is introduced, as is a new set of top dollar values ($500 for Rounds 1-2, $750 for Round 3, and $1,000 thereafter). The minimum value is $50, and unique values include $225, $325, $375, and $425.
 * 4) The puzzle board is now gray with 39 trilons on three rows and a single light border. The trilons show green sparkles for unused spaces, a solid white for unrevealed letters, and black letters on a white background. Once a contestant solves the puzzle, all letters light up and the unrevealed ones are turned around to a portion of "Give It One".
 * 5) 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-screen; a "SOLD" tag marks prizes already purchased.
 * While the puzzle board is designed to be mechanical, this element is not completed by the time of taping. Susan Stafford is hired to turn the letters.
 * John Rhineheart is producer, while Marty Pasetta directs. It is not known who produced or directed the Shopper's Bazaar pilot.
 * Edd is drunk during these pilots, as he recounts in his autobiography Kookie No More. On the first taping, he makes faces at the camera; on the second, he makes noises as the Wheel spins. He also bullies at least one contestant into spinning again, yelling "No! You only have $300! You can't solve yet!"
 * 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, and her bosses agree by November 18 on one condition – Chuck is host, not Edd. (It is rumored that Edd was caught reciting his vowels backstage by Merv.)
 * Both pilots are known to exist; clips from one of them were shown during the nighttime version's ceremonial 3,000th show (November 20, 1998), which includes contestant Roseanne solving PRINCESS ANNE for $825.

1975
January 1975 :
 * Wheel of Fortune debuts on January 6, replacing Jeopardy! as per contract but in the 10:30 AM slot formerly held by Winning Streak. Aside from Chuck hosting, there are only four changes:
 * 1) The show's theme song is changed to "Big Wheels" by Alan Thicke, who also supplies the show's other music cues.
 * 2) The Wheel's values are moved around a bit, with the minimum now $25. $50 and $75 spaces are also present.
 * 3) The puzzle board trilons now turn clockwise instead of counterclockwise.
 * 4) 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.
 * January 6 has the first discarded puzzle. As mentioned by Charlie during the credits, the contestant who solved it was credited with her winnings, a new puzzle was substituted, and the program edited.
 * The January 6 show is known to exist, as clips of it were used in the show's E! True Hollywood Story.
 * On January 6 or shortly thereafter, Giorgio begins providing Susan's wardrobe.

February 1975 :

March 1975 :
 * For the week of March 10, in honor of St. Patrick's Day, Wheel and NBC's other daytime games (then 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 and their names placed in a drum; a name is drawn and asked a question for $100,000. An incorrect answer means that another name is drawn and another question asked, continuing as necessary until a correct answer is given. Chuck and NBC's other hosts (Art James, Jim McKrell, Alex Trebek, Peter Marshall, and Geoff Edwards) appear to provide moral support for their respective champions.

April 1975 :

May 1975 :

June 1975 :

July 1975 :
 * The July 15 show is known to be held on audio tape by Archival Television Audio, Inc.

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

September 1975 :
 * Beginning on September 1, Chuck appears as a panelist for the week on Celebrity Sweepstakes; the September 5 show is held on audio tape by Archival Television Audio, Inc.
 * By about this point, 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. These games confirm several aspects about the show at the time of their release, including:
 * 1) The categories in use at the time: Event, Fictional Character, Landmark, Person, Phrase, Place, Thing, and Title. Outside sources have said that the show began with six categories, so it is probable that Fictional Character and Landmark were the first two "additional" ones.
 * 2) The Round 1 Wheel layout is changed, with the minimum now $100: The tan $75 becomes a second $500, the sole $25 becomes $300, the red $50 becomes $150, the yellow $75 becomes $200, and the blue $50 becomes $100. Based on available info about Round 4, the top value is still $1,000 and the sole $50 is increased to $150.
 * 3) The shopping round begins allowing contestants to put 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. From this point until the removal of the shopping rounds, most contestants choose the gift certificate.
 * 4) Any instance of punctuation is still ignored (i.e., FISHERMANS WHARF instead of FISHERMAN'S WHARF).
 * 5) The original score displays, shown in the same color as the respective contestant's arrow, are still in use.
 * 6) Buy A Vowel is still present on the Wheel, and the special spaces still have their original appearance.
 * 7) The original, thin-flap "pointers" (as Chuck referred to them on the premiere) are still present.

October 1975 :

November 1975 :
 * November 3 is NBC's Daytime Gigantic Game Gala, a week-long celebration involving Wheel and the network's other games (then Celebrity Sweepstakes, The Hollywood Squares, The Magnificent Marble Machine, and 3 for the Money).
 * For the week of November 3, Wheel airs for a full hour from 10:30-11:30 AM; High Rollers, which normally occupies the 11:00 slot, does not air. This results in the only known week with three hour-long daytime network games: Wheel, The Hollywood Squares (celebrating its 10th year), and The Price Is Right (permanent).
 * On November 7, Chuck and Susan play Celebrity Sweepstakes for home viewers (the only non-soap opera personalities to do so). The home players are chosen at random from various phone books and placed in a drum, then drawn to determine who plays for who; in addition to in-show winnings, the winners receive an extra $75,000 for first place, $20,000 for second, and $5,000 for third.

December 1975 :
 * On December 1, Wheel again expands to 11:30, taking over the High Rollers slot again. Changes made for the hour-long format, which were likely also in place for the week of November 3, are believed to include the following:
 * Three contestants play three rounds each in the first half-hour, apparently with $500, $1,000, and $1,500 as the top values. A second set of contestants is introduced in the second half-hour, also playing three rounds for these amounts.
 * The winners of each half-hour segment play a head-to-head round with $2,000 as top value. Also, one wedge is placed on the Wheel which corresponds to a prize; if a contestant hits Bankrupt while holding a Prize wedge, it is placed back on the Wheel.
 * The winner of the head-to-head round plays a Bonus Round with the same rules as the Star Bonus Round, which is described in further detail below.

1976
January 1976 :
 * On January 19, Wheel returns to a half-hour, now at 11:00 AM; High Rollers returns at 10:30. All new elements added in the hour-long format are retired, although $2,000 returns in 1979 and the Prize wedge is reintroduced in 1983.

February 1976 :

March 1976 :

April 1976 :

May 1976 :

June 1976 :
 * On June 3, 4, or 6, contestant Linda sets a single-round winnings record of $8,325.
 * By June 7 (#368), the Wheel has gone through several changes: [[Image:Round1-76.jpg|thumb|right]]
 * 1) Buy A Vowel and the second Lose A Turn are removed; the Round 1 layout replaces Buy A Vowel with $400, while Round 2 replaces both Buy A Vowel wedges and the second Lose A Turn by a pair of $300 wedges and a red $500.
 * 2) Bankrupt, Lose A Turn, and Free Spin adopt their normal appearances.
 * 3) Top dollar in Rounds 2 and 3 are increased to $1,000 and $1,500, respectively. These may have held over from the hour-long episodes.
 * 4) The "pointers" are changed to white, teardrop-shaped "flippers".
 * By June 7, the contestant score displays are changed to white.
 * 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 displays are still in use. While looking similar to the style introduced in 1985, they are only shown sporadically due to being on art cards.
 * On June 7: [[Image:Killtheumpire.jpg|thumb|right|"KILL THE VAMPIRE"?]]
 * Charlie's introduction of Chuck is "Now, let's meet the host of Wheel of Fortune, Chuck Woolery!" (This may have been the original opening, but this is uncertain.)
 * There is a noticeable layer of dust on top of the contestant arrows.
 * During Round 1, a buzzer sounds on a correct letter.
 * With only vowels remaining, contestant Gerry mis-solves the Round 1 puzzle KILL THE UMPIRE as KILL THE VAMPIRE.
 * Following Round 1, Chuck mentions getting letters from people who don't like seeing him hug contestants. He responds by saying "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, contestant Lee loses a then-very high total of $2,750 to a 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.
 * Returning champion Linda sets a new half-hour total winnings record of $23,200.
 * The closing segment has Chuck and Susan saying goodbye as the camera zooms out to show the Wheel spinning. This effect is dropped by 1978, but returns in 1980.
 * 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. As per the network's standard at the time, the ticket and fee plugs were cut out and the credits were crunched.

 * On the above episode, Lose A Turn has a white stripe down the left side and a thick black line down the right.
 * At some point between March 16 and April 6, the Star Bonus token is introduced; the token is on the red $100 next to Free Spin during Rounds 1-2 and $150 during 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 at least three known instances of the Star Bonus Round being played, one of which is mentioned below. [[Image:StarBonus4778.jpg|thumb|right]]

 * In Round 3, the contestants are shown turning their backs during the mid-round outro.

 * On August 4, the show moves back to 11:00 AM.
 * Don Morrow fills in as announcer for the week of August 4.
 * The August 4 show opens with Chuck joking about the show's demise.
 * Jack Clark takes over as announcer on August 11. Charlie and Johnny Gilbert are known to have filled in when Jack was unavailable.
 * 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; the situation is rectified by implementing a new, high-capacity phone line.
 * On August 18:
 * 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 when the puzzle is solved.
 * Contestant Mike is originally from South Africa, but living in Canada.
 * 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 18, 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.
 * Alex Trebek fills in for Chuck around this point, most likely the week of the 25th.

September 1980 :

October 1980 :

November 1980 :
 * November 3-6 (and possibly October 31 as well) features NBC game show hosts playing for members of the audience, who also determine what prizes to buy in the shopping rounds. Each match pits the host against two contestants who play normally. Wink Martindale and Jim Perry are among the participants, and it is rumored that Art Fleming also played.
 * 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 contestant Art and wins $1,400.
 * By November 6, the electric-guitar commercial cue is moved to the mid-show consolation prize plug (although it is barely audible on November 6). The December 4, 1979 cue is now the only one used for commercial breaks.
 * As of November 6, the contestant score displays are still the same color as they were from at least June 1976.
 * November 7 begins the show's first Armed Forces "Week", plugged as such despite beginning on a Friday.
 * Immediately following the Armed Forces episodes is Celebrity Week on the Town.
 * The returning champion from November 6 probably returns on the 24th.

December 1980 :
 * By December 18, and probably for the entire month, the set is again decorated for Christmas. The curtain has a wreath on it, and the foliage behind the contestants is thicker than it was in 1979.
 * By December 18, the contestant score displays are tinted yellow.
 * On December 18:
 * Chuck's cord gets caught on the nearby car as he makes his entrance.
 * 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.
 * Contestant 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 contestant score displays return to their normal color.
 * By December 24, the commercial cues are changed up once again: For the first time in over a year, the show's theme 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:
 * Contestant 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.
 * There is a commercial break during Round 1, the earliest known instance of this happening.
 * Chuck mistakenly says that the top dollar for Round 2 is $2,000.
 * The earliest known instance of a puzzle containing multiple punctuation marks, in this case Round 2's SLEIGHBELLS RING ARE YOU LIST'NIN' (Quotation). It is also very large for the era, using all but nine trilons, and is solved by contestant Linda for a then-massive $6,700.
 * After Linda buys a $6,168 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.
 * No music is played during the commercial outro after Round 4.

1981
January 1981 :

February 1981 :

March 1981 :

April 1981 :
 * By April 21, the electric-guitar cue returns to use for all commercial breaks and the mid-show car plug.
 * 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!"
 * Contestant 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.
 * What is believed to be the lowest one-round score up to this point: $250.
 * Contestant 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.
 * As of April 21, the Speed-Up round split-screen shot still has the puzzle on top and the players on the bottom.

May 1981 :
 * May 11 is San Francisco Week, where contestants from that city are flown in to compete. This is the earliest known instance of such a week.

June 1981 :
 * June 22 is San Antonio Week, done the same way as San Francisco Week.

July 1981 :

August 1981 :

September 1981 :
 * September 21 is Portland Week, recorded 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, contestant Linda prepares 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 electric-guitar cue is still used for at least one commercial break (in this case, during Round 3).
 * As of the above episode, the $2,000 space is still red and the nearby $250 is still yellowish.

October 1981 :

November 1981 :

December 1981 :
 * December 14 is Christmas Wish Week. The current Bonus Round is in place by this point and referred to as the "Christmas Wish Bonus", implying that it was introduced this week.
 * From December 16-22, Pat Sajak appears on Password Plus and is credited as being "from Wheel of Fortune".
 * On December 18:
 * After contestant Terry says he will be a "househusband" in January, Chuck says that he will be a "househusband" on December 26.
 * 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.
 * The earliest known instance of three puzzles in the same category: Rounds 2 and 4 are Thing, while the Bonus Round is Things.
 * After the game, Susan mentions the set changes to take effect the following Monday.
 * By December 18, the commercial break cues are changed up once again: The show's theme returns, used after Rounds 1 and 3 plus the mid-show catalog plug and after the Bonus Round; the December 4, 1979 cue also returns, used after Round 2.
 * As of December 18, shopping rounds are still done after the Speed-Up, even if the 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 does not use the Wheel logo, instead showing Susan walking in a light New York shower.
 * On December 21, the set is overhauled:
 * 1) The various prize platforms are replaced by a single, large, three-sided turntable at center stage.
 * 2) The puzzle board is replaced with a new one containing another row and another nine trilons, for a total of 48 (11 on the top and bottom rows, 13 in the middle two). It uses the same trilon designs and letter font as the old one.
 * 3) The contestant area is changed to starbursts of the same color as the respective contestant's arrow with many white "beams" spreading out in all directions from each color. They continue to display the money put "on account" or total champion winnings.
 * On December 21, 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 day will be his last show. After the game, Chuck and Susan show footage of their visit in New York. "Sleigh Ride" is played during the fee plugs and credits.
 * By December 25, the December 4, 1979 cue is once again put to use for all commercial breaks and the mid-show plug for the airline which flew the players to California.
 * By December 25, the $2,000 space and the nearby $250 swap positions, resulting in $250 becoming red and $2,000 becoming yellowish.
 * On at least December 25, Susan does not make her entrance through the curtain; rather, she walks over from next to the puzzle board as the turntable spins.
 * December 25 is Chuck's last show. Among the events that day:
 * Susan's entrance includes her blowing kisses to Chuck.
 * There is a commercial break during Round 1, which Chuck erroneously states as having never happened before; one such break occurred on December 24, 1980, and probably other times.
 * During Round 2, Chuck quips that one of the contestants (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 such a confidant over the previous years; he then thanks several people, including John Rhineheart, Nancy Jones, Charlie O'Donnell, Jack Clark, and Merv Griffin. Chuck follows this by admitting that leaving Wheel is "one of the most difficult things I've ever done".
 * No Bonus Round is played.
 * "We Wish You a Merry Christmas" is played during the fee plugs and credits.
 * During the credits, 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 the words "Teen Week" in quotation marks.
 * On December 28, Pat Sajak becomes the show's host. Among the events that day:
 * 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; 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 is lit up.
 * During Round 2, the camera zooms out from the $550 space while an incorrect letter is called.
 * Contestant Jay opts not to buy the $2,195 hot tub after Round 2, 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 Jay not buying the hot tub.
 * The Bonus Round is played from the yellow contestant backdrop, which was likely also the case during the weeks of December 14 and 21.
 * By December 28, the Final Spin rules are slightly altered: rounds beginning as a Speed-Up are 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.
 * As of December 28, the money graphic is still green and still zooms in.
 * As of December 28, Roselon Industries still provides Susan's wardrobe.
 * During Pat's first week, a contestant buys a vowel which is not in the puzzle and Pat tells the player to spin again. He is then told by Nancy Jones that the player has in fact lost their turn.
 * During Pat's first week, a contestant mis-solves the puzzle ABRAHAM LINCOLN as ABRAHAM BINCOLN with only the B's and L's missing.

1982
January 1982 :
 * Claudia, the returning champion from Chuck's last episode, presumably returns on January 4.
 * It is believed that the practice of playing the Bonus Round in front of the puzzle board began on January 4; it was definitely in place before March 11.
 * There is a Hawaii Week at some point this month, as promoted by Pat during his week on Password Plus. This was most likely done identically to the 1981 [City] Weeks, by flying in contestants from Hawaii.

February 1982 :

March 1982 :
 * By March 11:
 * The money graphic becomes white and "flips" toward the camera.
 * "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 credits are slightly changed to show the Wheel spinning below Pat, Susan and the day's champion.
 * March 11 is the first known instance of a puzzle using all four lines of the puzzle board, in this case Round 2's A LITTLE KNOWLEDGE IS A DANGEROUS THING.
 * On March 11 and 12, 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 March 11) as the Wheel stops. Except for the zoom, an identical shot was used by mistake on December 17, 2003.
 * March 11 has the first known instance of a contestant calling R, S, T, L, N and E in the Bonus Round, although not in that order.
 * On March 12:
 * 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.
 * Pat accidentally tells a contestant that an L has already been called in Round 1. He corrects himself later on in the round, and says that the answer simply does not have an L in it.
 * Contestant Bill purchases 11 items 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.
 * Bill sweeps the main game and wins a bedroom set in the Bonus Round. The music cue used for the bedroom set is the theme from Blank Check.
 * A contestant calls for O in the Bonus Round, the first known instance of a contestant calling a vowel other than E under the original 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 March 12, Climax begins providing Susan's wardrobe; considering the strange outfits she wears on March 11 and 12, along with Pat's comments on the latter show, this association was probably short-lived.

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

May 1982 :

June 1982 :

July 1982 :

August 1982 :

September 1982 :
 * A voiceover during the credits of the show listed as March 12 promotes an NFL preseason game that night between the Giants and Dolphins, a match known to have been held on September 3. Either the shows listed as March 11-12 were reran on September 2-3, or the March dates are incorrect and they originally aired in September.

October 1982 :
 * October 22 is Susan's last episode, as she wishes to pursue charity work. As seen on the show's E! True Hollywood Story, she was presented with a bouquet of flowers at the end of the show by Nancy Jones and many of the crew said goodbye.
 * From October 25-December 10, Summer Bartholomew, Vicki McCarty, and Vanna White take turns as guest co-host. Given the six-week span, it is likely that each of them filled in for two weeks.

November 1982 :

December 1982 :
 * December 13 is Philadelphia Week, which is the same as previous [City] Weeks minus the returning champion from December 10. The open shows Pat in that city, waving in front of a large fountain.
 * December 13 (Episode #2,016) is Vanna's first permanent episode, recorded on December 5. Among the events that day:
 * Her 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.
 * Footage from Pat's trip to Philadelphia is shown just before the credits, and this is where Pat signs off.
 * On at least December 13 and 29, there is a large pot of flowers behind each player.
 * By December 13:
 * The money graphic and Wheel logo begin to be displayed in different colors.
 * The commercial cues are changed up once again: The show's theme 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 27 is Teen Week, which uses a version of what would eventually become the Friday Finals: Three contestants compete on Monday-Thursday, and the three biggest winners return on Friday to play for savings bonds. Despite this format, the opening for the week (see below) shows 14 contestants; it would hence be reasonable to assume that two of them were 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. The practice of the hosts being introduced together would become permanent on the nighttime show in late 1989.
 * On at least December 29, the contestants stand on boxes, a fact which Pat points out after Round 1.
 * On December 29, 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.
 * December 29 has the first known instance of a four-line puzzle in a Speed-Up round. The answer is THE NINA THE PINTA AND THE SANTA MARIA, which is also the first known instance of a puzzle being completely filled-in before the solve.
 * 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, recorded on January 9.

February 1983 :

March 1983 :
 * March 28 is Teen Week.

April 1983 :
 * On April 1:
 * During Round 1, both a ding and the applause machine are suddenly 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, with $1,000 as the top value for Rounds 3-4 and $2,000 for Round 5.
 * In Round 3, contestant Trevor mis-solves the puzzle JUICE NEWTON as JOYCE NEWTON. A turn later, the "only vowels remain" beep fails to sound, although a stagehand can be heard telling Pat that only vowels remain. Contestant Juanita solves the puzzle for $50.
 * The Bonus Round is played for a four-person vacation to Disneyland worth $5,302, which is not won.
 * After the Bonus Round, 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 "house minimum" is (increased to?) $200.
 * 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.
 * New Leaf begins providing Vanna's wardrobe.

May 1983 :
 * At some point this month, probably a Tuesday and definitely before the week of May 23, the Wheel's spikes are rewelded 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").
 * On an episode from this month, known to be the day after the above:
 * During the open, Pat honks a car's horn right after Jack introduces him.
 * Pat does the demo spin with both feet off the floor. Following the overhead shot, the camera returns to the position it had just before.
 * Before Round 2, the puzzle chime accidentally sounds while Pat is talking 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, contestant Paul calls for either A (a vowel) 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. The next player, Jackie, calls for H and loses her turn as well.
 * Pat's Final Spin lands on Lose A Turn.
 * After Round 3, contestant 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".

June 1983 :

July 1983 :

August 1983 :
 * On August 8, Alan Thicke's music package is replaced with a new package composed by Griffin, 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" in October 1987. The instrumentation is also more "chirpy" for the first few months.

September 1983 :
 * The nighttime version debuts on September 19 in most markets, September 12 in others.

October 1983 :
 * On October 31:
 * During Round 1, Pat forgets to ask a contestant 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; despite this, the prize cue is still playing.
 * The bonus puzzle, WIN LOSE OR DRAW, uses all four lines of the puzzle board. It is not known why this was done, as the answer would fit easily on two.
 * By October 31, Jon Wesley begins providing Vanna's wardrobe.

November 1983 :
 * November 1 begins the Home Puzzle Contest, the show's first home-viewer sweepstakes. Portions of a puzzle are revealed each day this week, and the winners receive a microwave oven with accessories; a set of kitchen appliances; or a "video package" including a television and a video tape recorder.
 * November 7 is likely the first Couples Week, with husband/wife teams ranging from engaged to being married for 40 years. The format is similar to Teen Week, with the highest-scoring couples returning on Friday for a chance at a 1984 "American luxury car". The opening shot of the puzzle board has COUPLES WEEK on the middle two lines.
 * Oddly, the opening on at least November 9 shows just eight couples. It is likely that the opening was reshot throughout the week as couples were eliminated.
 * On November 9:
 * During Round 1, the first couple'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.
 * All four puzzles are Phrase.
 * The winning couple plays for a big-screen TV in the Bonus Round, but fail to solve TOP SECRET with T__ SE_RET showing. The husband then remarks "Oh, that was so easy!"
 * By November 9, a bumper is added in the middle of each episode which shows the turntable spinning into place for the next round with a Wheel of Fortune logo at the top. The Wheel 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.
 * By November 9, Giorgio of Beverly Hills begins providing Vanna's wardrobe.
 * As of November 9, the Merv Griffin Productions logo used in the credit roll is still the original one.

December 1983 :

1984
January 1984 :
 * On an episode from around January:
 * The Wheel spins very slowly during the open.
 * Before Round 2, the audience gets overly excited after 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. For no apparent reason, contestant Doug gets buzzed for calling a repeated R.
 * During the Speed-Up round, Doug forgets to say the last A when solving NEW DELHI INDIA. Oddly, the camera cuts to a close-up of him as he says the correct answer.

February 1984 :
 * 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 sex 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, implying that one of the ladies was a standby.
 * On February 29:
 * The Wheel spins very slowly during the open and close.
 * Before Round 2, Pat brings up a question from contestant 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 game.
 * The Round 2 puzzle is SARAH PURCELL, co-host of the 1977-78 game show The Better Sex. While the appearance of her name 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's mics are left on during the credits, and they can be heard talking with the contestant.
 * By February 29, Jon Wesley begins providing Vanna's wardrobe again.
 * By February 29, the Merv Griffin Productions logo in the credits has been replaced by a full-color drawing of a griffin against a black background.

March 1984 :

April 1984 :
 * On a Thursday episode, known to be from between April 12 and May 24:
 * During his interview, contestant Bill accidentally calls Pat "Jack". After Round 1, Pat refers to Jack as "Pat".
 * During Round 3, it takes a total of six spins before a correct letter is called.
 * There are two sets of repeated categories: Phrase for Rounds 1 and 2, Thing for Rounds 3 and 4 plus the Bonus Round.
 * Pat does his sign-off immediately after the Bonus Round.
 * By the above episode, Climax begins providing Vanna's wardrobe again.
 * As of the above episode, the contestant backdrops still look the same as they did in December 1981.

May 1984 :
 * Beginning May 7, Pat and Vanna play Dream House for the first week of a two-week All-Star Charity Tournament against Jamie Farr and Kari Michaelson; Pat and Vanna play for the American Cancer Society (winning $9,450), while Jamie and Kari play for the Juvenile Diabetes Foundation (winning $10,300).

June 1984 :

July 1984 :

August 1984 :
 * Around this point, "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.

September 1984 :
 * By September 10, 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.
 * By about this point, contestants have generally stopped using "as in" when calling letters (i.e., "P as in Pat").

October 1984 :

November 1984 :

December 1984 :
 * As of December 25, the logo shown after the money graphic is still the original one.
 * As of December 25, the category strips still use the computerized font.

1985
January 1985 :

February 1985 :
 * On February 1, Rounds 1, 2, and 4 are all Phrase.
 * By February 1:
 * The Wheel logo shown after the money graphic is updated to an animated one.
 * Winning totals after the Bonus Round begin to be displayed in the Helvetica font. The category strips are also changed to Helvetica, albeit a thinner version with a shadow effect.
 * The mid-show bumper begins spelling out the show's title one letter at a time horizontally.
 * February 4 is Couples Week.

March 1985 :

April 1985 :
 * On April 1, Pat makes an April Fools Joke by saying that he and Vanna are married.

May 1985 :

June 1985 :
 * At some point during the Summer, Alex Trebek fills in for Pat, most likely for one episode.

July 1985 :

August 1985 :

September 1985 :
 * By September 9, the category strips are upgraded to a bolder form of Helvetica with a white outline. The strips are generally color-coordinated to Vanna's dress.

October 1985 :

November 1985 :

December 1985 :
 * On December 25, Jack Clark appears on stage at the end of the show with Pat and Vanna to wish everyone a Merry Christmas.

1986
January 1986 :

February 1986 :

March 1986 :

April 1986 :

May 1986 :

June 1986 :
 * June 16 is Teen Week.
 * Susan fills in for the week of June 16; Vanna is absent due to a then-recent plane crash which killed her spouse, John Gibson.
 * On at least June 20, no credit is given for Susan's wardrobe.
 * June 20 has two sets of repeated categories: Phrase in Round 1 and the Bonus Round, Things in Round 3, and Thing in Round 4.
 * As of June 20, the contestant backdrops still look the same as they did in September 1984.
 * As of June 20, the $175 space 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; she then gives him several gifts that she found for him.

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

August 1986 :

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.
 * By September 8, the contestant backdrops are altered to streamline the "jagged" edges; the resulting appearance closely resembles a sunflower.
 * By September 8, the Wheel wedges are recolored, replacing some peach and tan wedges with pink and purple. Other wedge colors are brightened as well. In addition, the $175 space in Round 1 is increased to $500 and $1,500 moves to the opposite side of Bankrupt.
 * September 15 is the debut of the daytime Jackpot wedge, which begins at $1,000 and increases by $1,000 each day until claimed.

October 1986 :
 * On a Monday episode from the Fall:
 * Only one prize is bought after Round 1 – a 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.

November 1986 :
 * On November 13:
 * 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 the next day. The returning champion, who is not one of the tied contestants, is informed 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 (or the above episode, whichever is later), the Merv Griffin Enterprises logo still looks the same as it did on February 29, 1984.
 * November 17 is College Week.

December 1986 :
 * December 22 is Teen Week, recorded on November 22. Some general notes about this week:
 * The opening, using the same structure as previous Teen Weeks, shows 13 players in front of the puzzle board. The "odd one out", Guru, does not play at all this week.
 * As it is also Christmas week, 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.
 * Neither the animated Wheel logo or Jackpot wedge are used.
 * Pat Richards provides Vanna's wardrobe on December 22, and Climax on December 23-24. It would appear that by this point, there are several rotating sponsors for her outfits.
 * On December 22:
 * 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.
 * Rounds 1 and 3 are Things and Thing, respectively.
 * The Bonus Round timer continues to play for about two seconds after the time's-up buzzer.
 * Only $1,900 is won by the day's winner, and $2,700 awarded altogether.
 * The Wheel can be heard loudly spinning as Pat and Vanna sign off.
 * By December 22, the Merv Griffin Enterprises logo has been altered to add the line "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 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, a contestant's call of M is misheard as N, and the N is briefly put on the chyron.
 * After the solve, one of the winner'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:
 * The opening Wheel shot suddenly jumps backward when the transition appears.
 * During Round 2, Pat forgets to ask contestant 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:
 * While doing the opening spin, Pat accidentally says $450 is top dollar for Round 1 instead of $750; after realizing his mistake, he adds "Don't hit Bankrupt, if you do...I'm liable to give you this jacket."
 * 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 :
 * At some point in 1987, two games in a row end in a tie. This results in a champion playing five games.

February 1987 :
 * 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.

March 1987 :
 * On March 30, it takes six turns to reveal any letters in the Round 1 puzzle HO CHI MINH. With only the O missing, a contestant mispronounces the name; the next contestant solves for the house minimum of $200, then buys the ceramic Dalmatian and puts the rest on a gift certificate.

April 1987 :
 * On April 27, 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 :

June 1987 :
 * On June 5, a contestant wins a Jackpot of $21,000. This is believed to be the highest total ever achieved with the Jackpot.

July 1987 :

August 1987 :

September 1987 :

October 1987 :

November 1987 :
 * On November 29 and 30, a contestant wins the Jackpot for two days in a row.

December 1987 :

1988
January 1988 :

February 1988 :

March 1988 :

April 1988 :

May 1988 : 
 * Jack's last daytime show airs this month (possibly the 6th), with Charlie O'Donnell filling in afterward. First-run nighttime shows with Jack continue through June 3, and early Summer repeats have him doing the replacement fee plugs.

June 1988 :

July 1988 :
 * Jack Clark dies on July 21.

August 1988 :
 * Johnny Gilbert fills in for one week this month, possibly the week of the 29th.

September 1988 :
 * By September 5, M.G. Kelly begins filling in as announcer.
 * 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 then ask the contestant for three more consonants and a vowel. The first daytime bonus puzzle under these rules is OREO COOKIES, which is not solved.

November 1988 :

December 1988 :

1989
January 1989 :
 * January 9 (Episode #3,564) is Pat's last daytime show, recorded around October 1988. He steps down from daytime to host his short-lived talk show, The Pat Sajak Show, which debuts that night. Among the events that day:
 * Appropriately, the Round 1 puzzle is TAKE GOOD CARE OF YOURSELF.
 * Following the Bonus Round, Pat makes out with Vanna until series creator Merv Griffin walks up and pokes 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.
 * Several comments during the show mention "Friday" and "Monday", implying an airdate of January 6; this was probably an error due to the below.
 * January 10 is Rolf Benirschke's first show, recorded on December 14, 1988. Promos aired during the week of January 2 advertising his debut, "starting Tuesday". Among the events on his first day:
 * M.G.'s introductory spiel 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, and Round 1 begins in the second segment.

February 1989 :
 * An episode during Rolf's tenure has the earliest 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 different episodes during Rolf's tenure, the game ends in a tie. On the first instance, Rolf admits on-camera that he does not know what to do.
 * There is a Teen Week during Rolf's tenure. On one of those episodes, he congratulates himself for hitting $2,000 in a Final Spin; a contestant then points out that Rolf is looking at the wrong arrow and has actually hit Bankrupt.
 * February 17 is M.G.'s last episode; Charlie O'Donnell returns on February 20.
 * On February 22, contestant Lois gets three Free Spins in Round 1.
 * On February 22, Rolf's Final Spin lands on Lose A Turn.
 * As of February 22, Augustus still provides Rolf's wardrobe.

March 1989 :

April 1989 :

May 1989 :
 * The May 9 show is Episode #3,649.
 * On May 22, NBC announces the show's cancellation due to declining ratings; on May 24, CBS announces the show's return "beginning sometime this Summer".

June 1989 :
 * June 30 is Rolf's last episode, the last with the shopping format, and the last taped at NBC Studios in Burbank. It is also the last use of $2,000 as a cash value.
 * By June 30, Rick Pallack begins providing the host's wardrobe.
 * On June 30, Charlie says his name while signing off, the only known instance of any daytime announcer doing so.

July 1989 :
 * On July 17, the show moves to CBS at its original timeslot of 10:30 AM. Among the changes are:
 * 1) Bob Goen becomes the show's host, a hiring which had been announced on July 7.
 * 2) The show moves to CBS Studio 33, the same studio in which The Price Is Right has taped since 1972.
 * 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" beep, Final Spin bells and category chimes are all changed to the current ones. The "time's up" buzzer in the Bonus Round is now two short buzzes, instead of the "wrong letter" buzzer.
 * 5) "Changing Keys" and the puzzle-solve cue are re-arranged. This and all subsequent versions of "Changing Keys" end on a single note instead of the puzzle-solve cue. For the time being, the bridge of "Changing Keys" plays when Vanna walks out.
 * 6) The turntable is dropped, replaced by a grouping of prizes. The host's area now has a backdrop of silver chevrons, while the contestant backdrops are upgraded to chevron shapes; the midsection of each backdrop still shows the total for returning champions. In addition, the host's podium and the spaces between the players' score displays are are changed to a solid brown design.
 * 7) The contestant nametags are now parallelogram-shaped, with white letters on a gray background.
 * 8) The Wheel offers far less than it did previously: $500 is once again top value for Round 1 and also for Round 2, $1,000 for Round 3, and $1,250 thereafter. For the first time since 1975, $50 and $75 appear on the Wheel.
 * 9) Prize wedges are introduced to daytime, with a new prize added in each of the first four rounds. The first one offered is a trip to Lake Tahoe, worth $916.
 * 10) The Free Spin disc becomes green, with "SPIN" in the center and "Free" on the top and bottom in yellow script.
 * 11) As a result of the reduced Wheel values, vowels now cost $200.
 * 12) The Bonus Round now offers subcompact cars and a cash prize of $5,000. The latter is displayed on a green disc suspended from the ceiling, which rotates counterclockwise. While the nighttime version changes Bonus Round prize selection to a random draw from envelopes spelling W-H-E-E-L in September 1989, daytime still allows contestants to pick their own bonus prize until the daytime version is canceled. Picking the cash is not as common on daytime as it had been on nighttime at this point.
 * 13) The opening retains the "old" style from Rolf's last show, with Charlie's intro changed to "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!"
 * 14) 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 nonexistent values such as $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.
 * 15) The overhead Wheel shot is retained during the credits, but now has a zoomed in shot where only the last digit of each cash wedge is visible (though the "50" in $1250 can be seen), as well as the last few letters of the Bankrupt, Lose A Turn, and prize wedges (if any remain). The closing, like the early months of the nighttime version's all-cash format at the time, still retains the usual disclaimer from the shopping era, but without the reference to "Gift certificates do not include sales tax."
 * The returning champion from Rolf's last episode does not return on July 17.
 * July 17 is the debut of Person/Fictional Character, which is renamed to its current name of Star/Role by 1990.
 * On July 17, Pat makes a cameo before Round 3 to wish Bob good luck.
 * 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..."
 * On July 18, the two-digit values are given diamonds and the yellow $50 near Bankrupt is increased to $300. This $300 wedge is "off-model", with a larger dollar sign and smaller 3. In the closing, Charlie notes that "This show has been edited for broadcast."
 * Charlie's intro changes again on the 19th. "Lots of exciting prizes" is changed to "wonderful and exciting prizes", and the next several 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..."
 * On July 19, the contestant nametag letters change from white to black, presumably because the white lettering was hard to see.
 * On July 19, the Round 1 Wheel undergoes several value changes: The "off-model" $300 is swapped with the $125 next to it and becomes an "on-model" $50♦, 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.
 * By July 21, and until at least the first week of nighttime episodes in September, some puzzles have zeroes accidentally loaded in for O's. These can be discerned as being much wider and rounder than the regular O's.
 * On July 21, Same Name begins using an ampersand instead of spelling out AND. The answer is EGG & VANNA WHITE.

August 1989 :
 * By August 29, 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 song is slightly updated with a new opening version, as the closing version that was first used continues to be used in the closing. Charlie's spiel is now "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 camera pans from the Wheel to the board as the "new" logo, now the regular one, appears; cuts to the audience as the wedges fly back out of the graphic; then cuts again to center stage while Charlie introduces Bob.
 * By August 29, the purple $50♦ in Round 1 is increased to $300. Only one each of $50♦ and $75♦ remain on the Wheel.
 * August 31 is the last known appearance of Nickname and the first known appearance of Person/Title.
 * On August 31, two Wheel prizes are introduced in Round 3.

September 1989 :
 * By September 18, the Round 1 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 decreased to $100.

October 1989 :
 * On October 16, the tan Free Spin wedge becomes a single green Free Spin token placed on various amounts. The spot formerly holding the wedge becomes $400.

November 1989 :

December 1989 :

1990
January 1990 :
 * As of January 4, vowels still cost $200.

February 1990 :

March 1990 :
 * By March 5, the show holds a Soap Stars Week with cast members from The Young and the Restless, The Bold and the Beautiful, Guiding Light, and As the World Turns. Based on this and a print ad, it likely utilized the Friday Finals format with each soap getting its own episode. An article from March 7 notes that contestant Jay Hammer (Guiding Light) donated his winnings to his alma mater – the University of the Pacific in Stockton, California.

April 1990 :

May 1990 :

June 1990 :

July 1990 :
 * July 2 is Armed Forces Week, where contestants are called from the audience to play. After each round, the two players who do not solve the puzzle are eliminated, and two new contestants are called to replace them.
 * By July 5, the cost of buying a vowel is reduced to $100.
 * As of July 5, the contestant area still looks the same as it did on July 17, 1989.
 * Around this point, a contestant is known to have solved NICK NOLTE STARRING IN Q&A with only one letter (most likely the N's) revealed.

August 1990 :

September 1990 :
 * By September 3, several changes occur:
 * 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 displays are also connected to each other, with no space between.
 * 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 rules for Prize wedges are changed to have players call a right letter before claiming the wedge, instead of picking it up automatically and then calling a letter for the dollar value underneath.
 * 4) The Bonus Round chevron backdrops, which have been in use since the first episode, now have lights that flash during the opening, bonus prize descriptions, and closing.

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

November 1990 :

December 1990 :

1991
January 1991 :
 * January 11's bonus puzzle (KING OF THE ROAD) uses three lines of the puzzle board, a practice which was almost entirely abandoned after mid-1989.
 * January 11 is the last episode where the credits mention that the show is "Recorded at CBS Television City in Hollywood, California".
 * On January 14, the show moves back to NBC but continues to tape in CBS Studio 33. Unlike the move to CBS, the return to NBC results in only three changes:
 * 1) The original episode tally, in place since 1975, is discarded in favor of a 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!"
 * 3) The opening is slightly altered to superimpose the logo over a shot of the day's contestants.
 * 4) In addition, the champion from January 11 returns to play again.

February 1991 :
 * There is a Teen Week at some point this month. During this week, Bob does not do the opening spin and the usual backdrop behind him is not present.
 * By the Teen Week, the opening is slightly altered to remove the superimposed Wheel logo from the shot of the day's contestants.
 * On the last day of Teen Week, a contestant wins $11,802 in the main game.
 * On the last day of Teen Week, the contestant's letters fill in the bonus puzzle SNACK BAR completely.
 * The February 26 show is Episode #DT032.

March 1991 :
 * The weeks of March 11 and 18 are the Cashpot Sweepstakes, where home viewers enter to solve each day's Cashpot puzzle. As a result, only one round is played in the first segment, and it is believed that some games only go to three rounds.
 * By March 11, the value of a prize now flashes on a chyron if a contestant picks it up.
 * On March 19, 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 and 3; Round 2's prize (a ring) starts on the purple $100 and moves to the blue $100, with the Round 3 prize (a spa) taking the ring's place in Round 3.

April 1991 :

May 1991 :
 * By May 23, Bob has stopped doing the opening spin entirely.
 * On May 23, the cameras switch to the over-the-Wheel shot too soon during a spin, catching it in "mid-flight".
 * May 27 has a very rare instance of a four-line puzzle in the Speed-Up round.

June 1991 :

July 1991 :

August 1991 :
 * August 30 is the last first-run episode. Repeats air for the next three weeks, through September 20.
 * It was once rumored that Wheel continued through December 31, 1993 in first-run or repeats and, while there have been cases of affiliates showing repeats of cancelled network games (the original versions of Jeopardy! and Gambit), this is (as far as anyone can tell) merely a bit of wishful thinking.

Wheel 2000 (1997-98)

 * While Wheel 2000 did air in daytime on network television, it is considered a derivative of the nighttime show. See Wheel 2000.
