On edit: I should have said "Perception of Credibility" in the title.. Sorry...
Interesting study by the Pew Center...
The falloff in credibility affects news organizations in most sectors: national newspapers, such as the New York Times and USA Today, all three cable news outlets, as well as the broadcast TV networks and NPR.
Across all 13 news organizations included in the survey, the average positive believability rating (3 or 4 on a 4-point scale) is 56%. In 2010, the average positive rating was 62%. A decade ago, the average rating for the news organizations tested was 71%.
Since 2002, every news outlet’s believability rating has suffered a double-digit drop, except for local daily newspapers and local TV news. The New York Times was not included in this survey until 2004, but its believability rating has fallen by 13 points since then.
Not surprisingly, the partly lines are pretty well defined with more Republicans favoring Fox News and dismissing MSNBC along with the reverse being true for Democrats.
I do find it a bit surprising that NPR, long held to be a bastion of liberalism in the view of Republicans, had a higher favorability among them. Good radio is good radio, I guess (I'm biased, having worked for an NPR affiliate as news director).
Anyway, I just thought I'd throw it out there.
