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.
Game Show Network
Game Show Network launched at 7:00 p.m. ET on December 1, 1994. The first aired game show was "What's My Line?". From 1994 until about 1997, the network aired classic pre-1972 game shows as well as game shows made after 1972, most of which came from the Mark Goodson–Bill Todman library. The network aired game shows in a 24-hour cycle, and also used live interstitials as wraparound programming. In its first few months, GSN's commercials consisted of public service announcements (PSAs), promotions for its programming and commercials related to network parent company Sony. By 1995, when the network began to expand, the network began accepting conventional advertising as it gained new sponsorships. On March 17, 1997, the Game Show Network rebranded with a new presentation package and a new logo (which had the network's name in boxes and a colorful swirling ball) and a new slogan "All Play, All Day". While the logo changed, its programming remained unchanged, the network also debuted new promos and new idents on that day, which were designed by graphics agency Lee Hunt Associates.
