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.
Hal Block
In March 1950, producers of the new game show "What's My Line?" hired Block for its fourth episode to add humor to the show's format. With a panel previously consisting of journalists, a politician and a poet, reviewers had criticized the show as bland. After a rocky start, "What's My Line?" became one of the top-rated shows on television. Critics praised his work; the "Chicago Sun-Times" called Block the "freshest new personality in TV."
