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.
What's My Line?
In addition to the television version, "What's My Line" was also broadcast on network radio for a short time. From May 20, 1952 to August 27, an NBC Radio version was produced on Tuesday nights with the same cast as the TV version. After August 27, the program was then broadcast live on CBS Radio on Wednesday nights at 8:00 PM for 10 months concluding July 1, 1953. The radio version is notable for the only appearances of Marlene Dietrich, Constance Bennett, and Marlon Brando.
