But, according to a press release from the Public Policy Polling group -- the group Fox cites for this claim -- the truth is less black-and-white.
First off, the survey group offers up this headline: "Is Fox the most trusted name in news?" Then it goes on to explain that the only TV news group getting a "positive" review is Fox News. It adds that "49% of Americans say they trust Fox News to 37% who didn't; 15% were unsure."
Hmmm... does that really sound like a majority positive review? Among 10 people, four could trust one TV news operation; while there could be three votes for other networks.
Most trusted, then, sounds right. But to be fair -- Fox is the most trusted among news organizations we generally really don't believe. Not exactly the best endorsement.
Every single other news organization was in the red -- so to speak. More of the survey participants said they didn't trust CNN, NBC, CBS, and ABC, then those who didn't - averaging around 34% positive, to 44% negative. But a definite chunk of them, on average 21%, said they weren't sure about any of these networks.
Party lines went the way one expects for Fox, according to the poll: 74% of Republicans trust Fox, with only 30% of Democrats saying they believe the right-leaning network. (Now, there could be an interesting story: the other 26% of Republicans who may not trust Fox.)
Positive TV polls or reviews for shows or networks should always be taken with a grain -- or an entire mine -- of salt.
Fox also uses the "We Report. You Decide" advertising line. I trust viewers still believe that line.
