Double Dare is an American television game show, produced by Mark Goodson—Bill Todman Productions, that ran from 1976 to 1977 on CBS. Alex Trebek was the host, with Johnny Olson and later Gene Wood announcing. Two contestants, each in separate isolation booths, attempted to correctly identify a person, place or thing based on one-sentence clues that were given to them, one at a time, on an electronic gameboard. The correct response was shown to the home audience before the first clue was given. The clues would typically begin with an obscure bit of trivia concerning the subject, with each subsequent clue offering more information and making it easier for the contestants to identify the subject. Each subject had ten total clues associated with it.
