Great Scott! Fringe Tops Friday Ratings

It didn’t draw the 1.21 gigaviewers I had hoped for, but Fox’s Fringe nonetheless won the night in the demos with its Friday debut.

Fringe delivered a 1.9 rating in the coveted 18-to-49 demo, up 12 percent from its last Thursday outing and building slightly on its lead-in, Kitchen Nightmares. Overall, the spooktacular series — which this week guest-starred Back To The Future‘s Christopher Lloyd — drew 4.83 million total viewers.

Elsewhere on the newly freaky Friday….

* NBC’s CBS’s’ Medium walked into the light with a finale audience of  7.76 million total viewers, making it the night’s most watched program (with CSI: NY serving up a repeat and Blue Bloods temporarily test-driving Wednesdays).

* The aforementioned Kitchen Nightmares led the 8 o’clock time period in the demos. In fact, Kitchen Nightmares and Fringe combined to give Fox its best average Friday rating since March 2008 (!).

* The double-helping of CSI: NY repeats won the 9 and 10 pm slots in total viewers, with audiences of 7.2 million and 6.6 mil.
