Someone upthread really put their finger on it...Simpsons at its worst often beats most tv comedies (animated or otherwise) four-fingered hands down. Kinda like SNL, it has its off years but still manages to come back...i don't think anyone in 1998 would have expected the show would still be on 10 years later with no signs of quitting. I think the Simpsons' main competition is with itself...its had some very intensely high creative peaks that it becomes really hard after awhile to match that level.
...and though this was back on page 1, i can't let this go without commenting on it..."While Fox News has a definite conservative bias, most other mainstream news has a liberal bias" - that is one of my biggest pet peeves when i hear it precisely because that's one of the Big Myths of our time - the idea of a "liberal media" is a fraudulent and cwrefully crafted claim/strategy that dates back decades and over time has not only gained more credibility in the general public's minds due to years of steamrolling that concept into us but the more its claimed the less it turns out to be true precisely because (1) Fox News, as a specifically created conservative news channel drives its influence into other networks (2) the charge of "liberal bias" has become so prevalent and bandied about so frequently that most news sources end up over-compensating with self-censorship and in the process leans more rightward...one of the major goals of the whole "liberal bias" lie/strategy (3) as almost all media/news sources are swallowed up into conglomerates and ultimately owned by one of five companies, there's much less dissent and independant thought/reporting - with the big fish dictating direction to all the small guppies. For just about the past decade, an American has to look at papers/news from outside the US to really get a clear view of the whole story!
There's some really excellent books on the subject, chief among them Eric Alterman's "What Liberal Media?" (and if you're not into heavy reads, you could also try Al Frankin's "Lies and the Lying Liers Who Tell Them" which in many ways covers a lot of the same material just in a less scholarly and more comedic tone) and David Brock's "The Republican Noise Machine" which makes a great companion piece to WLM as it traces the history of the whole "liberal media" myth and its snowball effect on modern media. The works of Greg Palast are also excellent in terms of seeing the kind of stories that get censored by our "liberal media" and what kind of stuff should be on our front pages if today's media had any kind of spine.
