I’ve Got a Secret is a panel game show produced by Mark Goodson and Bill
Todman for CBS television. It was a derivative of What’s My Line?. Instead of
celebrity panelists trying to determine a contestant’s occupation, the panel
tries to determine a contestant’s "secret", from unusual to embarrassing.
The original version ran until April 3, 1967. It began broadcasting in black and
white and switched to a color format in 1966. The show was originally hosted
by radio and television personality Garry Moore.
