From the Pew study:

• One of CNN's slogans is, "The Most Trusted Name in News." According to the Pew study, that's exactly what CNN is.

CNN topped the media believability list, with 30% responding, "believe all or most." That figure slightly tops 60 Minutes, but CBS News as a whole found itself near the bottom. MSNBC had 24% and FNC 23%.

Still, the figures in the index are down across the board (in 1998 CNN was tops with 42%).

"Over the last 10 years, however, virtually every news organization or program has seen its credibility marks decline," says the study.
