The latest Thursday-night ratings race netted out the same as last week, with CBS' Survivor: Cook Islands (15.74 million viewers), ABC's Grey's Anatomy (22.82 mil) and NBC's ER (14.37 mil) topping their respective hours, and Ugly Betty (13.81 mil), CSI (21.58 mil) and Shark (14.14 mil) again proving to be formidable second-placers.

The most noteworthy week-to-week movement came from Smallville (4.93 million, up 330,000) and Supernatural (3.7 mil, up 400,000), while Six Degrees, hampered yet again by significant 10:30 tune-out (minus 2.1 million heads), slipped a half-mil from last week and is now down 34 percent from its Sept. 21 bow.
