The December 23, 1974 telecast of The $10,000 Pyramid saw the game moved to a new weekday time slot at 2:00pm (Eastern) on ABC and a new feature added to the show called "Big 7", which if a team picked a category where a special designated card was hidden beneath somewhere on the mini pyramid game board during the main game, the civilian contestant would be eligible to win a bonus prize if he/she successfully navigated the category. (The "Big 7" crossed over to Bill Cullen's Pyramid version beginning in September 1975, with an amount of available cash varying from season to season.) On Monday, January 19, 1976, the ABC daytime show doubled the stakes and now became known as The $20,000 Pyramid; the first celebrity guests on the retitled game’s first week were Jo Anne Worley and Bill Cullen. Aside from winning Emmies left and right (in May 1976 as "Outstanding Game/Audience Participation Program" and "Outstanding Direction in A Game/Audience Participation Program"), the show had really interesting moments during its ABC run: several high-scoring main games on record via some amazing tie-breakers (the Friday, July 4, 1975 broadcast featuring Lucie Arnaz and Anson Williams with a score 45-44, and the Monday, June 12, 1978 episode with a score 43-42 featuring Sandy Duncan and Nipsey Russell) and the quickest win at the big Pyramid on record (Billy Crystal in November 1977 with an amazing 26 seconds, while a few others have done it in 30 seconds). It also yielded several infamous events: in the Friday, December 19, 1975 episode, where celebrity guest Clifton Davis became the first of two known people to accidentally rip the leather straps off the clue giver's chair in The Winner's Circle (the second was Sandy Duncan), and in a 1977 episode where a very frustrated William Shatner, having blown a shot at 20 grand for his civilian partner in The Winner’s Circle, grabbed up his chair and tossed it onto the floor!
A network primetime celebrity half hour special, The All-Star Junior Pyramid, which aired on Sunday, September 2, 1979 at 7:30pm (Eastern) and featuring Susan Richardson and Tony Danza playing the game for charity with young future stars from the new ABC shows debuting in the fall of that year (one of them on that particular episode was a youthful looking Rob Lowe), turned out to be its only network primetime appearance and led to the daytime version reverting to a full-time Junior Partner Pyramid format featuring civilian adult-children teams (with no celebrities at all!!!!!) between Monday, October 1 and Friday, November 9, 1979. A special Celebrity Junior Pyramid week followed suit with celebrity guests Susan Richardson, LeVar Burton and Michael McKean, but, fortunately, beginning with the Monday, November 19, 1979 telecast, the daytime show went back into its normal $20,000 Pyramid format.
