Ratings: Mariah Carries 20/20 to Demo Win, Nikita Spies Gain, No Spike for Supernatural

Viewers of 20/20 apparently were twin-piqued by Mariah Carey and her babies, leading ABC’s newsmagazine to draw 7.6 million total viewers and a night-topping 2.1 demo rating — surging 59 and 75 percent from last Friday.

In total audience, however, Blue Bloods (10. mil/1.7) as usual led the night, though dipping a few percentage points.

Elsewhere on Friday:

* In its new, super-sized home, Extreme Makeover: Home Edition averaged 5.6 million viewers and a 1.4 demo rating across its two-hour run, up a bit from what ABC was doing here with sitcom reruns. (In the apples-and-oranges category, EM: HE‘s final Sunday foray drew 7.1 mil and a 1.9.)

* CBS’ Gifted Man (8.65 mil/1.2) drew a few more eyeballs while holding steady in the demo. Kitchen Nightmares (3.46 mil/1.4) was flat. Nikita, with 1.73 million viewers and a 0.6 rating, spied gains of 5 and 20 percent.

* CSI: NY dominated the 9 o’clock hour with 10.7 million total viewers and a 1.8 rating, up 6 percent week-to-week. Despite much buzz, facing a Fringe repeat (1.73 mil/0.5) and delivering a very bewitching hour, Supernatural (1.82 mil/0.7) dipped a tenth in the demo (but did gain some viewers). And yes, I was committed to working Spike into today’s ratings headline, come hell or high water.
