Shows such as Beverly Hills 90210, Full House, The Wonder Years, Wings, Mad About You, Home Improvement, Friends, Roseanne, Cheers, The Cosby Show, and America's Funniest Home Videos.
There were many, but the most popular were probably Cheers, Seifeld, Frasier, Cosby Show and Friends. The 90's actually had some of the biggest hit comedies of all-time, with these shows winning some of the most Emmy's ever won. The Wonder Years (although not so much a comedy) was another hit show.
