The Cosby Show is an American television sitcom starring Bill Cosby, which aired for eight seasons on NBC from September 20, 1984 until April 30, 1992. The show focuses on the Huxtable family, an upper middle-class African-American family living in Brooklyn, New York. The Cosby Show was based on comedy routines in Cosby's stand-up act, which in turn were based on his family life. The show spawned the spin-off A Different World, which ran for six seasons from 1987 to 1993. In many areas, reruns of the show have been discontinued as a result of the sexual assault allegations against Cosby.
