Spin-off
The Cosby Show's producers created a spin-off series called A Different World that was built around the "Denise" character (portrayed by actress Lisa Bonet), the second of the Huxtables' four daughters. Initially, the new program dealt with Denise's life at Hillman College, the fictional historically black college from which her father, mother, and paternal grandfather had graduated. Denise was written out of A Different World after its inaugural season, due to Bonet's pregnancy, and the following season was revamped, with the addition of director Debbie Allen and new characters. Denise later became a recurring character on The Cosby Show for seasons four and five, and a regular again in seasons six and seven.
