So, looks like MSNBC has beat FNC for the first time in 17 years.

MSNBC beat out Fox News last week in key ratings for first time in 17 years, topping its competitors in total average viewers for the first time since 2000, according to a news release from MSNBC.
MSNBC averaged 1,558,000 total viewers during the “sales day” (6 a.m. to 2 a.m.) between Dec. 17-21, while Fox News averaged 1,541,000 total viewers. CNN, meanwhile, averaged 975,000.

Among people between the ages of 25 and 54, a key demographic for cable news networks, MSNBC also finished the week as the No. 1.

In prime time (8 p.m. to 11 p.m.), MSNBC continued to lead Fox News and CNN in total viewers and among that key age group for the fourth week in a row.

I suspect that it’s because FNC viewers skew older - and to put it quite frankly, it’s a matter of attrition through simple mortality. FNC’s viewer demographic is - quite literally - dying off.
