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.
Frontline (U.S. TV program)
The program debuted in 1983, with NBC anchorwoman Jessica Savitch as the show's first host, but Savitch died later after the first-season finale. "PBS NewsHour"s Judy Woodruff took over as host in 1984, and hosted the program for five years, combining their job with a sub anchor place on "The MacNeil-Lehrer NewsHour" when Jim was away. In 1990, episodes of "Frontline" began airing without a host, and the narrator was left to introduce each episode.
