John Charles Daly
Daly's first foray into television was as a panelist on the game show "Celebrity Time". This led to a job in 1950 as the host and moderator on a new panel show produced by Goodson–Todman, "What's My Line?" The show lasted 17 years with Daly hosting all but four episodes of the weekly series.
Dorothy Kilgallen
Kilgallen became a panelist on the American television game show "What's My Line?" in 1950 (its first broadcast), which was telecast from New York City on the CBS television network until 1967. She remained on the show for 15 years (until her death).
