From a Pew analysis:Fox News dominates the ratings in prime-time cable, with popular hosts such as Bill OReilly and Sean Hannity. How have they responded to their own parent company being in the news?The answer is they havent considered it nearly as much of a story as their rivals.The Pew Research Centers Project for Excellence in Journalism analyzed the content of four hours of daily prime time and an hour a day of daytime programming. The analysis finds that the Murdoch- owned Fox News Channel devoted about one-fifth as much time to the story as MSNBC and about one-sixth as much time as CNN.Then again, could it be, just maybe, that Fox's rivals in the competitive cable news industry are hyping the ghastly ethical and criminal lapses of their foes? Confession all around!PS: Pew also examines the WSJ's shift in coverage since Murdoch bought the daily in 2007.
