I think there is a difference between objectivity and bias. Objectivity is simply information that is based upon something factual or observable rather than opinions or feelings.
If I am a hard left eco-warrior who publishes photographs of stream pollution from a mining operation am I biased? Sure, but the photos are still objective information. The mining operation is in fact polluting the river.
The problem, to me, is that too many 'news' organizations really are more accurately entertainment organizations who care more about eliciting emotional reactions than they do in providing actual information. Rush Limbaugh, for instance, who might talk about Obama being a Nazi Communist Antichrist who wants to suck out your brains. On the other side, I think you could point to someone like Rachel Maddow, who also , in my opinion, is a bit too interested in emotionality versus information.
What we really need to do is seek out information (regardless of bias) and then attempt to verify it via other sources. However, what most people seem to do is seek out opinions which reinforce whatever makes them feel good. That is why the main stream has become entertainers. It is what sells. The only main stream organization that I think produces decent information is NPR, but they are also the one which doesn't fully participate in the free market, so do not have to worry about making people feel good.
At any rate, with today's technologies there isn't any reason to get information through the filter of institutional interests or to wait that long to get it. Just plug directly into the journalists or news providers you trust.
