How do you explain the contradiction that the MainstreamMedia is bias both liberally and corporately?

Is being bias towards liberal ideas, corporate ideals and government agendas mutually exclusive?|||I haven't noticed any bias toward corporatism in the media. The mainstream media are corporations in themselves, why would they care about other corporations? They have nothing to gain from them, it's their ratings that matter. It seems to be a club that only liberals can advance in, however.|||The 'liberal media bias' has been demonstrated to be a fantasy any number of times. It's just a way for cons to dodge questions and it works. All they have to do is attack the media and the suckers fall for it every time.
