And here is the important part you left out.
FNC is an opinion based channel, most of the time. CNN and MSNBC do not do as much opinion based programing as FNC. IMO that is why FNC is so popular. The only pure fact show I can think of is Brit Humes show, the 1st 30 minutes of it any way.That finding may be partly related to a larger tendency at Fox on all kinds of stories that allows on-air personalities to offer their personal opinions. Seven out of 10 Fox stories reviewed in the study included opinions not attributed to reporting. That happened in less than one of 10 CNN stories and in less than one of three stories aired on MSNBC.
