Winner Take All is an American radio-television game show that ran from 1946 to 1952 on CBS and NBC. It was the first game show produced by the Mark Goodson-Bill Todman partnership. The series was originally hosted by Ward Wilson, but is best known for being the first game hosted by Bill Cullen. Although the game format was very simple, Winner Take All served as the genesis for many future game-show formats. It was the first game to use lockout devices, and the first to use returning champions. In July 1952, CBS launched a Saturday night version of the show, in addition to the regular Monday-Friday daytime broadcasts.
