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?
An Australian version hosted by John Barnes debuted on station TCN-9 in 1956 during the opening week of Australian television and ran until 1958. It was replaced by a long-running version of "To Tell the Truth". The archival status of this version is unclear.
