Ratings: Fringe Returns to Series Low, Grimm Plunges, CBS Dramas Dip

Fox’s Fringe, despite knock-out performances by Jasika Nicole and Jasika Nicole, dipped 4 percent week-to-week to draw 3.2 million total viewers and match its series-low 1.1 demo rating. P.S. It looks like the Observers have the iPhone 5 already, lucky dogs.

Of Friday’s other genre fare, both Nikita ( 1.5 mil and a 0.5) and Supernatural (1.63 mil/0.7) held steady. Grimm, however — despite having a better-watched lead-in (Who Do You Think You Are? and its 6 million viewers vs. Chuck, RIP) — dropped 20 percent this week to 4.73 mil and a 1.4.

Elsewhere on the night:

8 pm | A Gifted Man, with 8.4 million total viewers and a 1.2 rating, dipped 4 and 8 percent from its last fresh outing. Who Do You think You Are? Season 3 premiered to 6 mil/1.1. Shark Tank held steady with 5.2 mil/1.5. Kitchen Nightmares (3.85 mil/1.6) surged double digits, easily leading the hour in the demo.

9 pm | CSI: NY (10.2 mil/1.6) dipped 4 and 8 percent but topped the hour on both counts. ABC’s What Would You Do? placed a distant second with 5 mil/1.4.

10 pm | Blue Bloods led all of Friday in total viewers with (11.3 mil, down 7 percent) and tied 20/20 for the night’s best demo (1.7, down a tenth).
