I remember that! Give you more publicity.
What’s My Line? is a panel game show which originally ran in the United States on the CBS Television Network from 1950 to 1967, with several international versions and subsequent U.S. revivals. The game tasks celebrity panelists with questioning contestants in order to determine their occupations. It is the longest-running U.S. primetime network television game-show. Moderated by John Daly and with 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 for Best TV Show in 1962.
After its cancellation by CBS in 1967, it returned in syndication as a daily production which ran from 1968 until 1975. There have been several international versions, radio versions, and a live stage version.
In 2013, TV Guide ranked it #9 in its list of the 60 greatest game shows ever.
