From Wikipedia:
Pyramid is the collective name of a series of American television game shows in which contestants tried to guess a series of words or phrases, based on descriptions that were given to them by their teammates. The title refers to the show's game board, featuring six categories arranged in a triangular fashion. Most different versions of the show included the various dollar values of their top prize in their titles, e.g., The $100,000 Pyramid. As a whole, the series won nine Daytime Emmys for Outstanding Game Show, second only to Jeopardy!, which has won 11.
Dick Clark is the host most commonly associated with the show, having hosted most incarnations of it from 1973-1988; Bill Cullen hosted a 1974-1979 syndicated version of The $25,000 Pyramid, while John Davidson hosted a 1991 revival of The $100,000 Pyramid and the most recent revival (simply titled Pyramid) ran from 2002-2004 with Donny Osmond as host.
Two pilots for a new version of the format, hosted by Dean Cain and Tim Vincent, were taped in summer 2009 for CBS as a possible replacement for the canceled Guiding Light. In this version, the top prize was to be raised to $1,000,000. CBS passed on the two pilots and opted to move forward with a revival of Let's Make a Deal hosted by Wayne Brady.
