In Living Color likely inspired MAD TV and a lot of other sketch comedies; and indirectly kept (horrifically written and low rated) black sitcoms marketable post-Cosby. Also in retrospect had a fairly deep cast. Noreen from Seinfeld doing Kinison is quite the time capsule.
The Office I Love Lucy All In The Family Three's Company Sex and the City (yes, and I'm a guy) Honorable Mention: Carol Burnett, Jeffersons, Taxi, Cheers, Mad About You, Seinfeld (a bit overrated, though-Seinfeld can't act), Parks and Recreation
You'll get no disagreement from me. It always amazed me how he could keep a straight face when nobody else could.
I've been watching 3rd Rock From The Sun and to me it's easily the funniest sitcom ever It's so underrated
Its been forever since I watched this............gotta go back and watch. Kristen Johnston was a smoke show
I gotta add Impractical Jokers to this list. I agree with Family Guy, All in the Family, Barney Miller, and my all-time favorite, Hogan's Heroes!
