The Pew Research Center for the People & the Press has been tracking views of press performance since 1985. In September 2011, Pew found that negative opinions about the performance of news organizations now match or surpass all-time highs.
In the poll, 66 percent of those surveyed stated news stories often are inaccurate and 77 percent think that news organizations tend to favor one side over the other. 80 percent of those surveyed said news organizations are often influenced by powerful people and organizations.
This negative opinion of the mass media has increased in recent years. In the Pew Research Center’s first survey on news attitudes in 1985, only 53 percent said that news organizations were often influenced by powerful people and organizations and tended to favor one side.
According to another poll conducted by Gallup in September 2011, Americans perceive a more liberal bias in the media than a conservative bias by a large margin since at least 2002. A significant majority of respondents perceive bias in the media.
