That strategy seems to be paying off, the L.A. Times noted.  According to Nielsen, Fox News has averaged 1.66 million weekday primetime viewers this year — up 14% from 2007.  Meanwhile CNN’s audience has grown by 40% to 1.06 million in 2008, and MSNBC’s viewership has increased 41% to 713,000.

The current cable news ratings increases extend a trend that began in 2004, when Fox News earned higher ratings for its coverage of the Republican convention than network broadcasters.
