Just because pundits like Limbaugh, Hannity, and Beck on the right, and Maddow, Olbermann, etc, on the left, appear on News stations, that does not make their program's news.
The line has become incredibly blurred between "news", and editorial "opinion" advocacy/editorial/propaganda programming.
Broadcast news programming has changed dramatically over recent years, starting with the ending of the Fairness Doctrine, to the point that many people in the public seem unable to distinguish between news and opinion, or facts and propaganda.
The unfortunate reality is that media corporations put profits first, and since sensationalism sells better than rational moderated debate, the effect is an increasingly polarized and dumbed-down nation where emotion triumphs over reason, and the corporate interests of the media conglomerates and their advertisers dictate who is allowed to say what over the public airwaves.
