 "I ve Got a Secret" debuted on the heels of the successful "What s My Line?" Though "Secret" had somewhat similar rules, there were other elements that gave the show its own distinctive flavor. As with "Line," four celebrity panelists try to guess an unknown-to-them secret, which the contestant (or sometimes group of contestants) whispered in the host s ear; the secret was always shown to the television and studio audience. Each panelist has one 30-second period to ask questions that will help them try to guess the secret; if a panelist fails to guess the secret before the buzzer sounds, the contestant(s) receive(s) $20 and the next panelist gets a turn. The process repeats until either the secret is guessed or if all four panelists are unable to guess the secret, meaning the contestant receives the maximum payout of $80 (during the early years, each panelist had two questioning periods, with $10 paid per unsuccessful try). Usually, a skit or demonstration of the secret followed each story. During the final segment of the show, a celebrity guest revealed his/her own secret, each followed by a segment, in which the panelists participated. Like "What s My Line," "Secret" had millions of faithful viewers during its CBS run, and spawned a number of revivals (including a weekly syndicated series in 1972 and a 2000 revival on the Oxygen network). Reruns of the CBS series currently air as part of Game Show Network s Black and White Overnight programming block.
