I don't think objectivity from humans is possible, but the attempt to be fair is. That seems to be what's lacking: no one seems to notice that fairness is often missing, it's not important. What's important is finding an opinionated asshole one can use as an example. People who think it's alright to be close-minded, prejudiced, and cruel with invective aimed at 'the other side' are not going to want their newscasters being fair. They need role models who demonstrate how to properly behave like an opinionated asshole and who endorse that sort of image.

Maybe that talk show mentality was with us before talk shows, but it sure seems to me that talk shows were where the new gladiatorial games first started gaining popularity. It took a while before 'news' shows bought into the games, but it was inevitable. Insidious too. I think things have changed quite a bit. Others don't notice anything different. Ah well - perhaps Cronkite, Huntley, Brinkley, Reasoner, etc, were just as publically biased as news people of today and I was just too young to notice.
