10. 'A Different World'
In 1987, Lisa Bonet's Cosby Show character, Denise Huxtable, was sent off to attend school at Clair and Cliff's alma mater, Hillman College — and her own show. A Different World dealt with social and racial issues facing the students at the historically black college, and was one of the first shows to tackle the HIV/AIDs epidemic. Both Denise, and her enthusiastic and quick-speaking roommate Maggie (played by a young Marisa Tomei) left after the first season; thankfully, the show's supporting characters — Whitley Gilbert, Jaleesa, Coach Walter Oakes and the unforgettable style icon Dwayne Wayne — easily stepped into the spotlight, and kept things buzzing along for another five seasons.
