TV Ratings: 'Fringe,' 'Grimm' Down, 'Nikita' Holds Steady

Seeing modest gains in "Shark Tank" and "Primetime: What Would You Do," ABC dominated the adults 18-49 demo -- while Fox and NBC saw slight dips in their scripted fare.

ABC eked ahead of CBS in the advertiser-coveted 18-49 demo on Friday night, earning an evening average of 1.5, versus CBS' 1.4. But CBS was the clear winner with total viewers, averaging an audience of 8.4 million against ABC's 5.2 million. 

The final Fringe before next week's season finale slipped to a .9 rating in the 18-49 demo, down from last week's 1.0, and an audience of 2.9 million viewers. Lead-in The Finder also slipped a tenth, down to a .9. It had a total viewership of 4 million.

NBC saw similar drops of one-tenth across its lineup: Who Do You Think You Are ? scored a .9, down from 1.0 last week, and 4.8 million viewers. Dark, fairytale procedural Grimm earned a 1.3 in 18-49, down from 1.4, and a total audience of 4.8 million.

Only ABC saw audience gains in adults 18-49, both with their enterpreneurial reality show Shark Tank -- which scored a 1.7 in adults 18-49, up from last week's 1.4 -- and Primetime: What Would You Do?, which scored a 1.4, up from last week's 1.1.

CBS saw losses across the board in the 18-49 demo,  with Undercover Boss dipping from a 1.6 to a 1.4, and a total audience of 6.6 million viewers, and CSI: NY dropping two-tenths to a 1.5, with 8.6 million viewers. But those older-trending audiences won the night for the network in overall viewers.

Perpetual bubble series Nikita on The CW, meanwhile, was dead-even with last week, earning a .4 in adults 18-49. Supernatural held steady at .7, too.
