I would belive that Fox did provide balance, IF CNN did stifle conservative thought...but from what you can see of my link, that's clearly not the case.
The liberal voices on CNN (Carville and Begalla) are always balanced by counterparts on the right (Carlson, Kurtz, Novak). CNBC has Dennis Miller, who hasn't made a new joke in 8 years and is also a total Bush Mark. MSNBC has Joe Scarborough (R-Dead Intern), and Chris the Screamer Matthews. No liberal on these networks with their own show and ideology to send out practally unopposed. And talk radio is nearly 100% right wing.
If you can cite ONE news analysis show with an OBVIOUS Liberal Bias, let me know. There has been less discussion about Bush's financial past than ther has been about Clinton's. Clinton was investigated for 8 full years and then sorta lied about sex...he was impeached. Bush wasn't investigated until he sorta lied about why we went to war...now he is and the Conservative media is up in arms about the So-Called Liberal Media
The two largest media organizations in the US are Fox and Clear Channel...who have been allowed to grow solely because of de-regulation sponsored by republicans. And no one can argue that they don't have a blatant conservative bias.
The So-Called Liberal Media was coined back in the 60's by the conservative movement simply to work the crowd and to convince the media to "allow a true balanced voice." No one can deny the huge presence of a right-wing media, better financed and more vocal than a liberal one.
