You Bet Your Life is an American comedy quiz series that has aired on both radio and television. The original version was hosted by Groucho Marx of the Marx Brothers, with announcer and sidekick George Fenneman. The show debuted on ABC Radio on October 27, 1947, moved to CBS Radio debuting October 5, 1949, and went to NBC-TV and NBC Radio on October 4, 1950. Because of its simple format, it was possible to broadcast the show on both radio and television but not simultaneously. Many of the laughs on the television show were evoked by Groucho's facial reactions and other visual gimmicks. So the two versions were slightly different. The last episode in a radio format aired on June 10, 1960. The series continued on television for another year, recording the last season, beginning on September 22, 1960, with a new title, The Groucho Show.
