Ratings: Grey's Spin-off Trumps the Shark

This Thursday's ratings recap:• Survivor: Fiji topped the 8 o'clock hour with a typical 13.72 million total viewers, followed by a surging Ugly Betty (10.71 million, up 1.15 mil). • Earl (7.58 mil) was on par with a week ago, but as far as NBC's other unusually sized comedies, I'm at a loss to crunch the numbers. (Hey, they asked for it.)• Smallville (3.55 mil, -380K) and Supernatural (3.16 mil, -180K) both dipped a bit.• Despite being as heavy-handed as that backdoor Brady Bunch spin-off starring Ken Berry as the adoptive dad of a rainbow coalition of sons, the two-hour Grey's Anatomy averaged 20.97 million viewers, reclaiming its lead over CSI (18.87 mil, down a mil) and then besting 10 pm bully Shark (12.66 mil, slipping 1.6 mil). Let me interrupt here to ask: Are you feelin' the Grey's spin-off? Vote here.• ER took the plunge — to the tune of 1.3 mil — placing third behind Shark with eight million.
