Split Friday Leadership

CBS MOST-WATCHED; NBC TOPS AMONG ADULTS 18-49

CBS maintained its status at the most-watched network on this first Friday in December care of Undercover Boss, CSI: NY and Blue Bloods. But the older skew of the three hours was not enough to beat NBC for first among adults 18-49, which populated the evening with an encore of two-hour special SNL Christmas and newsmagazine Dateline.

Blue Bloods on CBS topped the evening in total viewers, with 11.07 million at 10 p.m., according to the fast affiliate results from Nielsen. And Undercover Boss on the Eye was first overall in the demo, with a 1.6 rating/6 share at 8 p.m.

As a reminder, midseason CBS drama Golden Boy moves into the Friday 9 p.m. hour (in place of CSI: NY, which concludes for the season or series) on March 8.

Elsewhere, ABC comedies Last Man Standing and Malibu Country remained perfectly compatible, albeit modest rated, with an average 6.32 million viewers and a 1.4/ 5 among adults 18-49 in the 8 p.m. hour. Next on the alphabet net was a repeat of relocated Shark Tank at 9 p.m., followed by granddaddy 20/20 at a No. 1 finish in the demo at 10 p.m. (with a 1.7/ 5). Fox could not compete, meanwhile, with Kitchen Nightmares and soon-to-conclude Fringe. Nor could The CW with relocated Nikita and an encore telecast of Arrow.
