What's My Line?
In 1980, Mark Goodson-Bill Todman Productions, creators of "What's My Line?", produced "That's My Line" which also highlighted the unusual occupations of ordinary people. However, the show was developed as a reality show and had no panel or game elements. "What's My Line?" announcer Johnny Olson was the announcer, and Bob Barker was the host for the show which ran for two seasons on CBS.
What's My Line?
The 876th and final CBS telecast of "What's My Line?" aired on September 3, 1967; it was highlighted by clips from past telecasts, a visit by the show's first contestants, a challenger from the New York unemployment office, and the final mystery guest, who was John Daly himself. Daly had always been the emergency mystery guest in case the scheduled guest was unable to appear on the live broadcast, but this had never occurred. Mark Goodson, Bill Todman and Johnny Olson appeared on-camera as well.
