query: Who was the first host of the game show "What's My Line?"?
passage: John Charles Daly
Daly's first foray into television was as a panelist on the game show Celebrity Time.[4] 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.
passage: What's My Line?
Starting in July 1959 and continuing for 8 straight years, until July 1967, when John Daly was due to appear in Moscow, the show would occasionally record episodes onto Quadruplex videotape for playback at a future date. This was then state-of-the-art technology, and Daly praised it upon his return from Moscow. In such instances, there would often be two shows a day; the "taped" one, followed immediately by the "live" one. The cast and crew began taking "Summer breaks" from the show in July 1961, through July 1967.
