I've Got a Secret is an American 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, as in What's My Line, the panel tried 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 CBS on June 19, 1952, and ran until April 3, 1967. The show began broadcasting in black and white and switched to color in 1966, when all commercial prime time network programs in the US began to be produced in color. The show was revived for the 1972–1973 season in once-a-week syndication and again from June 15 to July 6, 1976, as a summer replacement series on CBS. Oxygen launched a daily revival series in 2000, which ran until 2001. A second revival by GSN premiered on April 17, 2006, and aired new episodes daily until June 9, 2006. Hosts and panelists The show was originally hosted by radio and television personality Garry Moore. After several months of an ever-changing panel, game show host Bill Cullen, acerbic comedian Henry Morgan, TV hostess Faye Emerson, and actress Jayne Meadows became the four regular panelists. In 1958, Emerson left the show to star in a play and was replaced by actress Betsy Palmer. Later that year, Meadows relocated to the West Coast and was replaced by former Miss America Bess Myerson. At various times, guest hosts substituted for Moore, including panelists Cullen, Morgan and Palmer, among others. Additionally, other comedians and celebrities appeared as guests on the panel when others were away. The announcer for most of the 1952–67 run was John Cannon. Moore left the show after the 1963–64 season. After his comedy program The Garry Moore Show was canceled, Moore chose to retire from television to travel the world with his wife. Moore was replaced by Steve Allen, who left his own syndicated talk show to take over the game, on September 21, 1964. Allen also hosted the show during the 1972−73 revival. Former panelist Bill Cullen hosted the show for its brief 1976 CBS summer run. Frequent panelists on this revival were Richard Dawson, Henry Morgan, Pat Carroll, and Elaine Joyce. The version seen
