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.
Whose Line Is It Anyway? (U.S. TV series)
"Whose Line Is It Anyway?" returned to television, this time on The CW, with Colin Mochrie, Ryan Stiles, and Wayne Brady, and Aisha Tyler taking the role of the host. In addition to the traditional rotating fourth improv player (often drawn from same pool of regulars that appeared on the original show), a new feature was that of a "special guest". This fifth player would not necessarily have an improv background, but would still participate in some of the improv games.
