A report released Monday by the Pew Research Center on media coverage
over the past 5 years indicates that MSNBC (with the lowest overall
budget) relies 85 percent on "opinions" by their commentators and 15
percent on actual reporting of news events.

According to the study Fox News spends 55 percent of their air time on
commentary opinions and 45 percent on reporting of actual news.

CNN was rated as being the only cable network that spent more time
reporting the news than opinion commentary.

What a surprise.
