I happen to prefer Fox News over all the other Networks. Many people wrongly believe that Fair and Balanced means objective; it doesn't.
Fair and Balanced means that everyone is biased in one way or another, and knowing that, the journalist needs to give a fair assessment of the facts, and let the opposition be heard if you are to give an opinion.
Most people who hate Fox News never actually watch their News segments and think that Fox is nothing other than O'Reilly / Hannity 24/7. The fact of the matter is that their News is Fair and Balanced, but their appeal is that their commentators lean Right, unlike all other shows.
People watch Fox News because they know what they are getting: Fair and Balanced reporting. MSNBC, however, still calls Olbermann a News program.
