Groucho Marx - You Bet Your Life
Groucho Marx is one of many stars to make a radio broadcast their debut, only to move to TV once the radio show reached popularity. But Marx didn't go the usual route with a sitcom or talk show; rather, he made a name for himself hosting a game show called, You Bet Your Life. The show, broadcast on radio, originally aired in 1947, becoming a televised radio show in 1950.
