What's My Line? is a panel game show that originally ran in the United States, between 1950 and 1967, on CBS. The game show started in black and white and later in color, with subsequent U.S. revivals. The game uses celebrity panelists to question contestants in order to determine their occupation. The majority of the contestants were from the general public, but there was one weekly celebrity "mystery guest" for whom the panelists were blindfolded. It is on the list of longest-running U.S. primetime network television game-shows. Originally moderated by John Charles Daly and most frequently with regular panelists Dorothy Kilgallen, Arlene Francis, and Bennett Cerf, What's My Line? won three Emmy Awards for "Best Quiz or Audience Participation Show" in 1952, 1953, and 1958 and the Golden Globe Awards for Best TV Show in 1962.
