"Fox and CNN are not different flavors of news, they are different things entirely. News organizations with any legitimate claim to that title do not keep important information from the public based on which party it benefits. CNN — or primetime MSNBC — may be opinionated, but they remain fundamentally fact-based. Fox does not."
Fox is an imitation of the news style but it's something different in substance that makes viewers less informed about the world.
