Third quarter 2006 cable news ratings come out today. Comparisons to Q3 2005 could be skewed because ratings spiked last year in the aftermath of Hurricane Katrina.

"The gap between Fox News and CNN continues to narrow," according to a series of charts from CNN. In the 25-54 demo, the gap was 102 percent in Q3 2004, 55 percent in Q3 2005 (thanks in part to Katrina) and 46 percent in Q3 2006.
