Personally, I avoid network news because it's so awful. The dumbest internet boards on earth are every bit as informed and intelligent as most of what you see on CNN, for instance.
I don't think the Fairness Doctrine is quite the solution to the problem of the media's emphasis on entertainment/theater/controversy of news as opposed to the actual news, but I do think the evidence during its existance compared to how things have become without it argues rather strongly that it's better than nothing. Another thing to keep in mind is that the "5 o'clock news" is a remnant of the Fairness Doctrine -- there's nothing stopping that from disappearing or becoming a self-mockery in the next decade as well. In so far is that news is a public service, some outside intervention seems necessary. You wouldn't want a fire department in the business purely for the money, after all.
So there's the question of how you intervene, and whether or not the government should be involved. But I think to some extent government has to be, because who else has the authority to do the job? That doesn't mean you turn the news into parrots for some agenda (would that really be any worse than what we have?), but some set of rules established, and some sort of committee to enforce them... and hopefully something to make sure the committee stays in line as well. :lol
