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?
The program began with Daly and panel entering from off-stage as they were introduced. Prior to 1954, both panelists and host began the program in their seats, but this was changed, responding to letters asking what panelists looked like away from their seats. The first panelist would be introduced by the announcer following the show's introduction, and each panelist would introduce the next in turn, with the last introducing Daly. During his tenure, Hal Block sat in the final seat and began the practice of introducing Daly with a pun. Upon his departure, Bennett Cerf took over this position. Cerf's introductions of Daly were generally straightforward in his earliest years on the show, but as time went by Cerf expanded these introductions, often telling long jokes which he tied to Daly in some way.
