Here's a couple of teasers for you.
"Fox News plays by rules very different from the rest of the media. They are not constrained by facts; make few attempts at being empirical or data-based; intellectually, they affiliate themselves not so much with a school of political thought as a specific political party. The rest of the media might be educated and urban and therefore be left of center on social issues, but that is an ideological bias, not a partisan one. Its almost as if “Fair and Balanced,” which Fox News used as a slogan, was purposefully sarcastic. To quote Jon Stewart when he appeared on Fox News with Chris Wallace, he described Fox as: “A biased organization, relentlessly promoting an ideological agenda under the rubric of being a news organization.” I don’t see a lot to disagree with in that."
"Perhaps most telling is that Fox News viewers are very often less informed than those who do not consume news at all."
