One of the classic game shows (and one of the simplest), and the first hit for producers Mark Goodson and Bill Todman ('I've Got a Secret,' 'To Tell the Truth'). The panelists had to guess contestants' odd or not-so-odd jobs, then (while blindfolded) guess a celebrity guest's identity (New York Yankee Phil Rizzuto was the first). After its 17-year CBS run, 'Line' aired for another seven in syndication. Panelist Arlene Francis stuck it out all 24 years.
