The media should be completely objective, but we know this is almost impossible. The news is reported by people. Those people have personal beliefs. While they are trained to be objective, speaking ones mind or putting a spin on a topic tends to be inevitable.
While the media as a whole might not be biased, certain stations might be more left or right winged. MSNBC is by far the most liberal station on the air. Anyone can tell this by simply watching their daily programs. Their own management has proclaimed they are "progressive" in order to counter Fox News. Fox News may be called conservative because they do have several opinion journalists and conservative anchors. These programs consistently bash the "left." The same can be said about newspapers and news magazines.
Politics and other issues may also be biased because most mass media today is supported by advertising. Those companies pay big dollars to get their product known and may have some say in what is being broadcasted. Any deal between news corps and advertisers must be made clear that the news is to remain objective and report ALL the news, even if the advertisers do not agree with it. That is the only way to be fair.
