“Over the last 10 years,” the just-released biennial news consumption survey from the Pew Research Center for the People and the Press determined, “virtually every news organization or program has seen its credibility marks decline”
and “Democrats continue to give most news organizations much higher credibility ratings than do Republicans.”
Based on past Pew polls, CNN touts itself as “the most trusted name in news,” but the percent who “believe all or most” of what CNN reports has fallen 12 points, to 30 percent, since Pew first posed the question in 1998.
Yet, in a sign of how far the news media have fallen in the eyes of the public, that puts CNN at the top of the 12 television news outlets analyzed, as well as above all the newspapers and online sources. Believability for ABC News, CBS News and NBC News is down six points over the past ten years, to 24 percent for ABC and NBC, 22 percent for CBS, but that's still better than the mere 18 percent who “believe all or most” of what they read in the New York Times.
The extensive polling conducted in May also discovered that the audiences for CNN and MSNBC, “which were heavily Democratic two years ago, have become even more so: fully 51 percent of CNN's regular viewers are Democrats while only 18 percent are Republicans. MSNBC's audience makeup is similar -- 45 percent of regular viewers of MSNBC are Democrats, 18 percent are Republicans” and “the regular audience for nightly network news also is now about two-to-one Democratic (45 percent vs. 22 percent Republican).”
