Quiz show scandals: Twenty-One game show contestant Charles Van Doren admits to a Congressional committee that he had been given questions and answers in advance.

The 1950s quiz show scandals were a series of scandals involving the producers and contestants of several popular American television quiz shows. These shows' producers secretly gave assistance to certain contestants in order to prearrange the shows' outcomes while still attempting to deceive the public into believing that these shows were objective and fair competitions. Producers fixed the shows sometimes with the free consent of contestants and out of various motives: improving ratings, greed, and the lack of regulations prohibiting such conspiracy in game show productions.

Twenty-One is an American game show originally hosted by Jack Barry that initially aired on NBC from 1956 to 1958. Produced by Jack Barry-Dan Enright Productions, the show featured two contestants playing against each other in separate isolation booths, answering general knowledge questions to earn 21 total points. The program became notorious when it was found to be rigged as part of the 1950s quiz show scandals, which nearly caused the demise of the entire genre in the wake of United States Senate investigations. The 1994 film Quiz Show is based on these events. A new version of the show aired on NBC in 2000 with Maury Povich as host.

A game show is a genre of broadcast viewing entertainment where contestants compete in a game for rewards. The shows are typically directed by a host, who explains the rules of the program as well as commentating and narrating where necessary. The history of the game shows dates back to the late 1930s when both radio and television game shows were broadcast. The genre became popular in the United States in the 1950s, becoming a regular feature of daytime television.

Charles Lincoln Van Doren was an American writer and editor who was involved in a television quiz show scandal in the 1950s. In 1959 he testified before the United States Congress that he had been given the correct answers by the producers of the NBC quiz show Twenty-One. Terminated by NBC, he joined Encyclopædia Britannica, Inc. in 1959, becoming a vice-president and writing and editing many books before retiring in 1982.
