ken007: Really? You think there are many people who
only watches Fox News and no other news channel?
Yes. Millions, in fact.
For most people, the news consists of the local paper and one news channel. It may be a local affiliate, it may be Fox, it may be CNN. In any of the above cases, these people are getting a tiny, biased fraction of what's going on in the world. Fox just happens to be the most biased of the bunch, but don't trick yourself: CNN is almost as bad as Fox these days, just on the opposite side of the narrow American spectrum.
Bottom line is, most people prefer to be lied to, because the lies support their existing beliefs.
If you want to be informed, get your news from a variety of sources, preferably, somewhere like Google News where you're getting it straight from AP. Aggregators like Digg and reddit work too, as long as you put forth the mental effort to filter out the liberal bias.
