Most of non-animated TV has gone to pot. But, there are a few gems, like Kevin said, L&O is good (even though I think there are too many spin-offs), and Desperate Housewives is a light relief from other dramas like 24 etc. Many people won't have heard of many of Little Britain or The Catherine Tate Show or any of those, but they are truly brilliant comedies, albeit they do use a heck of a lot of swearing and sex references, but if they can get my 75-year-old grandparents laughing, then they must be doing something right.
With the animation world though, I'd have to say it's a meh world. Many cartoons are extremely bland, lifeless in either comedy or action... although there are a few (Foster's, Xiaolin Showdown, Teen Titans, Samurai Jack JLU etc) which do perfect the comedy/drama well.
At least you Americans have some good TV... I know only the best TV (apart from Joey *shudders*) comes over here, but how much TV do you get from other countries (and don't say anime, that doesn't count). I'm probably becoming incomprehendable so I'll shut up now.
