partner Dan Enright as a weekly half-hour program for CBS' 1956–1957 schedule. The show was ultimately picked up by NBC and ran from September 12, 1956, to October 9, 1958, under the sponsorship of Pharmaceuticals, Inc., the makers of Geritol. The series finished at #21 in the Nielsen ratings for the 1957–1958 season. In 1958, Elfrida von Nardroff won $220,500 on the game show Twenty-One, more money than any other contestant on the show. After starting the 1958-59 season with an 8:30 Thursday night time slot, Twenty-One ran on October 2 and on October 9 before being abruptly canceled. An announcement broadcast a few hours before the scheduled October 16 program informed viewers that it would not be seen. A spokesman for Pharmaceuticals said, "Twenty-One was dropped because of a decline in ratings. We must admit that the investigation had something do with this decline," after the October 9 show had the lowest rating in its history. A prime-time version of Concentration was introduced in the 8:30 time slot on October 30, with Barry as the host and Pharmaceuticals' Geritol as the sponsor. Jim Lange hosted a pilot for an abandoned syndicated revival of the show in 1982. NBC revived the show in 2000 with Maury Povich as host, after ABC's Who Wants to Be a Millionaire, FOX's Greed, and CBS' Winning Lines proved that big-money game shows had once again become viable prime-time network fare. NBC aired first-run episodes through the end of May sweeps, after which the network declined to renew the series. Several unaired episodes aired on PAX TV in the summer of 2000. Scandal The initial broadcast of Twenty-One was played honestly, with no manipulation of the game by the producers. That broadcast was, in the words of Enright, "a dismal failure"; the first two contestants were not successful at answering questions. Show sponsor Geritol, upon seeing this opening-night performance, reportedly became furious with the results and demanded improvements. As a result, Twenty-One became not only rigged, but almost completely choreographed as well. Contestants were cast almost as if they were actors, and in fact were active and (usually) willing partners in the deception. They were given instructions as to how to dress, what to say to the host and when, which questions to answer correctly or miss, and even when to mop their brows. The producers could shut off the air conditioning to either booth
