Buffy the Vampire Slayer (started in the '90s, but still)
The Office (UK/US)
Daily Show w/ Jon Stewart and Colbert Report
also great: Friday Night Lights, Big Bang Theory, Brothers and Sisters, Carnivale, Chuck, Breaking Bad, Mad Men, Damages, Deadwood, Weeds, Six Feet Under, Californication, Alias, Will and Grace, Friends (more '90s, really), How I Met Your Mother, New Adventures of Old Christine, and the hardly-seen, gone-too-soon shows The Winner and Privileged and Pushing Daisies
I think for the next decade Community and Modern Family could make it.
