Wheel of Fortune is an American television game show created by Merv Griffin. Three contestants, occasionally three pairs of contestants, compete against each other to solve a word puzzle, similar to those seen in the game hangman. The name of the show comes from the large wheel that determines the dollar amounts and prizes won (or lost) by the contestants. The show debuted on January 6, 1975 on NBC's daytime schedule, replacing Griffin's own Jeopardy!, and spawned a daily syndicated version in 1983 which still airs today, mostly airing on ABC affiliates.
The 1974 pilots were hosted by Edd Byrnes and Susan Stafford; Byrnes was passed over due to being drunk during taping and was replaced for the series by Chuck Woolery. He left in 1981 replaced by Pat Sajak, and Stafford left ten months later, replaced by Vanna White.
Peter was one of the contestants on the show in "I Take Thee Quagmire", calling Sajak "Regis". The winning puzzle was "Alex Kerras in Webster". The shopping element shown in the episode, which led to Joan's employment, was eliminated from syndicated version in 1987 and from the network version in 1989. Since that time, players receive their game winnings in cash.
A British parody of Wheel is shown in "Family Guy Viewer Mail No. 2" with Wheel of Politeness, the contestants vying to let the others proceed first and then all apologizing to the audience.
