Fox News Hates Bloggers???

Many media companies found bloggers as a good and reliable source of news. I read a couple of months ago on the internet that high precentage of Italian public believe more the news read out blogs than these on news bulletins and official news broadcasters. In addition, British and Australian media like the BBC have endorsed bloggers, even there are some bloggers who started their journalism career with support of such media giants. There are also many American newspapers who enjoy this kind of cooperation between them and bloggers. However, what's the problem with FOX news channel? Why do they hate bloggerss by calling them "vicious", for example?
