Fast National ratings for Friday, January 30, 2009.

CBS' three powerhouse dramas were in repeats on Friday, but that didn't stop the Eye network from running off with an easy overall ratings win and a tie in the key demographic.

ABC and CBS both posted a 1.8 rating in the all-important 18-49 demographic, just ahead of the 1.6 rating for NBC and FOX's 1.3 rating. The CW's 0.6 rating trailed.

CBS swept the primetime hours starting at 8 p.m. with the 5.3/9 for "Ghost Whisperer." ABC's "Wife Swap" took second with a 3.3/8, nipping NBC's "Howie Do It" in the ratings, but not in total viewers. FOX was fourth with a "House" repeat, beating the 1.2/2 for new episodes of "Everybody Hates Chris" and "The Game" on The CW.

"Flashpoint" had a 5.3/9 in the 9 p.m. hour and also delivered the night's biggest audience to CBS. ABC's "20/20" was second with a 4.2/7. NBC's "Friday Night Lights" was third with a 2.5/4, holding off FOX's repeat of "Lie to Me." The CW's new "13 - Fear Is Real" had a 0.7/1.
