This is a pretty involved question. In short, yes the masses generally do believe the media. Generally the less educated a person is, the less critical people are. We are saturated by news purporting the truth. Most news outlets have a bias to them. Fox news, for example, tends to pander to the right of center ideology while John Stewart might view the world more liberally. The media is often uses information as a commodity. They tell us things to sell us things. We are frequently manipulated into believing we need a certain car or T.V to validate our very existence.
