<Tr> <Th> Related shows </Th> <Td> You Lie Like a Dog </Td> </Tr> <P> To Tell the Truth is an American television panel game show in which four celebrity panelists are presented with three contestants (the "team of challengers", each an individual or pair) and must identify which is the "central character" whose unusual occupation or experience has been read out by the show's moderator / host . When the panelists question the contestants, the two "impostors" may lie whereas the "central character" must tell the truth . The setup adds the "impostor" element to the format of What's My Line? and I've Got a Secret . </P> <P> The show was created by Bob Stewart and originally produced by Mark Goodson--Bill Todman Productions . It aired, on networks and in syndication, continuously from 1956 to 1978 and intermittently since then, reaching a total of 26 seasons in 2016 . As of 14 June 2016, it is one of two game shows in the United States to have aired at least one new episode in at least seven consecutive decades, the other being The Price is Right . </P> <P> Although there have been some variations in the rules over the years (including the addition of a secondary game in some versions), certain basic aspects have remained consistent throughout all versions of To Tell the Truth . Three challengers are introduced, all claiming to be the central character . The announcer typically asks the challengers, who stand side by side, "What is your name, please?" Each challenger then states, "My name is (central character's name)." The celebrity panelists then read along as the host reads aloud a signed affidavit about the central character . </P>
