The Miss USA beauty pageant aired on CBS from 1963 to 2002; during a large portion of that period, the telecast was often emceed by the host of one of the networks game shows. John Charles Daly hosted the show from 1963 to 1966, succeeded by Bob Barker from 1967 to 1987 (at which point Barker, an animal rights activist who eventually convinced producers of The Price Is Right to cease offering fur coats as prizes on the program, quit in a dispute over their use), Alan Thicke in 1988, Dick Clark from 1989 to 1993, and Bob Goen from 1994 to 1996. The pageants highest viewership was recorded in the early 1980s, when it regularly topped the Nielsen ratings on the week of its broadcast. Viewership dropped sharply throughout the 1990s and 2000s, from an estimated viewership of 20 million to an average of 7 million from 2000 to 2001. In 2002, Donald Trump (owner of the Miss USA pageants governing body, the Miss Universe Organization) brokered a new deal with NBC, giving it half-ownership of the Miss USA, Miss Universe and Miss Teen USA pageants and moving them to that network as part of an initial five-year contract, which began in 2003 and ended in 2015 after 12 years amid Trumps controversial remarks about Mexican immigrants during the launch of his Donald Trump presidential campaign, 2016.
