This survey  shows that Americans believe TV news and information is the most credible, followed by radio and daily newspapers. Sometimes you read these surveys and wonder what the actual questions were because it is hard to imagine that anyone believes TV news is more credible than print. I don't like to comment on content because everyone else does but here is one example of "credibility" in TV journalism. Last summer there was an unfortunate incident in Connecticut in which a woman literally had her face riped off by a pet chimpanzee owned by a friend. It was a crazy story and a very sad one for the injured woman and ultimately the chimpanzee. However, the breathless coverage it received from local news was similar to what you would expect if Bridgeport had fallen into the sea. There was live coverage from outside the home for weeks. There were people interviewed who had been in the house once and seen the chimpanzee, etc. It was a circus and the farthest thing from credible that can be imagined. My experience has been that most people are pretty smart and know the difference between entertainment and news, which makes me question these types of surveys.
