The cancellation of the competing quiz "Dotto" under similar allegations prompted a U.S. government investigation into both shows. The investigation similarly revealed that Revlon—the sponsor of "The $64,000 Question"—had instructed the show's producers to balance the game's questions more favorably towards contestants they felt would be more popular among viewers (although it did not fix games to the same extent as "Twenty-One"). The scandal resulted in regulations being implemented to prohibit the rigging of game shows and other contests by broadcasters.
