My favorite defunct shows: Burns and Allen, The Mary Tyler Moore Show, the Dick Van Dyke Show, Bob Newhart, Green Acres (go ahead, sneer, look down your noses, I don't care), and Amos & Andy. That last one will earn me some dislike, but I've known a lot of black people who thought it was a great show, too.

Modern shows: Law & Order - all three versions, Antiques Road Show -the American version, The Simpsons, Malcolm in the Middle, Keeping Up Appearances.

I would have put Friends and Frazier on the list, but I think both shows have overstayed their welcome.
