“What’s wrong with the mainstream media?”
Before answering this question, what is the mainstream media? Each newspaper (The Washington Post, The New York Times, etc.) and each news channels (CNN, MSNBC, etc.) has regular fluctuations in viewership, so that one is a news leader one month, but not another. I don’t have the viewer statistics long them, but my guess is that you are referencing, ABC News, PBS, CBS, CNN, MSNBC, Fox News, and the major newspapers previously mentioned. There are a variety of factors. One is ideology.
For example, yesterday USA Today published an opinion by ACLU lawyer Hina Shamsi that was critical of the Obama administration’s drone program. When was the last time you saw a mainstream opinion piece call taxation theft or the government illegitimate? There are limits to what the mainstream media allows.
Another factor is lack of skepticism, especially of government claims. For example, Media Matters for America, a progressive media watchdog group that will excoriate false conservative claims, but not liberal ones, reported October 30, 2007, ‘News outlets including CNN, the Associated Press, The New York Times, The Washington Post, and the Los Angeles Times uncritically quoted White House spokeswoman Dana Perino’s response to a question about an October 23 Federal Emergency Management Agency press conference, in which the questions were asked by FEMA staffers playing reporters. Perino said of the conference, “It is not a practice that we would employ here at the White House and we certainly don’t condone it.” But these news outlets failed to note previous Bush administration scandals involving “fake” reporting.’
Another factor is non-disclosure. For example, Media Matters reported July 2, 2008, ‘NBC’s Today and Nightly News and MSNBC Live aired segments in which correspondent Janet Shamlian reported live from an offshore drilling platform in the Gulf of Mexico. But while two of Shamlian’s reports included quotes from a Chevron spokesperson, none of her reports included an interview with or quote from environmental organizations or explained the “environmental concerns” that Shamlian acknowledged exist. Further, neither Shamlian nor the hosts and anchors disclosed that General Electric, which owns 80 percent of NBC Universal, also has an affiliated business unit that is invested in the acquisition and production of oil and natural gas and another that is a major supplier of equipment and services for the offshore drilling industry.’
If you want to see how a combination of these factors helped the Bush administration sell the Iraq War, watching the PBS documentary Buying the War.
