CBS

CBS (short for Columbia Broadcasting System) is a network which debuted in January 1927 as United Independent Broadcasters, quickly changed to Columbia Phonographic Broadcasting System. In 1928, the 16 radio stations were bought out by William S. Paley, who renamed it to the Columbia Broadcasting System.

Despite several controversies (most notably a 2004 episode of 60 Minutes questioning then-President George W. Bush's service in the National Guard), CBS is currently the highest-rated in the country with the most stable schedule out of all the major broadcast networks.

Wheel of Fortune
CBS was very quick to pick up the daytime show, announcing its renewal on that network only two days after NBC announced its cancellation due to declining ratings. While the show's renewal was announced on May 24, the hiring of new host Bob Goen was not announced until July 7.

The change of networks also resulted in a change of studios, from NBC Studios in Burbank to CBS Studio 33. The shopping format was also dropped in favor of a scaled-down version of the nighttime show's play-for-cash format, and all of the music and sound effects were replaced by new versions and compositions by series creator Merv Griffin.

Wheel debuted on July 17, replacing the 13-week revival of Now You See It hosted by Chuck Henry; the show originally used the NBC opening, but this was dropped at some point between July 21 and August 29. The program continued on CBS through January 11, 1991, after which it moved back to NBC.

Six years later, CBS assisted GSN in airing a children's version called Wheel 2000, hosted by David Sidoni and "Cyber Lucy" (Tanika Ray). This version ran from September 13, 1997 to September 1998.

(It should be noted that CBS also aired the 1950s game show called Wheel of Fortune, which has been noted as having several similarities to the subsequent Merv Griffin production.)
