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.
Mystery!
The first host of the show in 1980 was the NBC Today Show arts editor and film critic Gene Shalit. In the first broadcast, February 5, 1980, Shalit opened with the introduction: “Good evening. We’re about to set out on a series of entertaining mysteries—15 weeks of suspenseful, sophisticated, crafty conundrums that are darkly diabolical or amusing adventures with introductions that suddenly seem alarmingly alliterative.” Shalit left the show in 1981.
