I’ve Got a Secret is a panel game show produced by Mark Goodson and Bill Todman for CBS television.  Created by comedy writers Allan Sherman and Howard Merrill, it was a derivative of Goodson-Todman’s own panel show What’s My Line?.  Instead of celebrity panelists trying to determine a contestant’s occupation, the panel tries to determine a contestant’s “secret”: something that is unusual, amazing, embarrassing, or humorous about that person.

The original version of I’ve Got a Secret premiered on June 19th, 1952 and ran until April 3rd, 1967.  This version began broadcasting in black and white and switched to a color format in 1966, by which time virtually all commercial network programs were being shown in color.

The show was revived for the 1972–1973 season in once-a-week syndication.
