Although it earned ratings a bit lower than a week ago, ABC grabbed another Thursday night win--thanks to its big tag team of "Grey's Anatomy" and "Private Practice."

"Grey's Anatomy" grabbed a Nielsen 5.9/15 and "Private Practice" took a 4.4/12 for the second week of its big crossover programming event. A week before, "Grey" earned a 6.0/14, while "Practice" took a 5.8/15.

All this gave ABC a win with a 4.2/11, ahead of CBS' 3.9/10. A week ago, ABC had a 4.7/12, while CBS had a 4.1/11.

While CBS' "Survivor: Tocantins" was able to maintain its numbers at 4.5/12 versus a week ago, "CSI" took a tumble to a 4.4/11 from a 4.9/12. CBS' "Eleventh Hour" slipped a bit to 2.6/7 from a 2.7/7.

Fox improved from last week with its "The 40th NAACP Image Awards" as well as new episodes of "Bones" and "Hell's Kitchen." It finished the night with a 3.0/8.

NBC was next with a 2.5/6 for the night, as the network slipped a bit from a week ago. All this was thanks to two of its main shows in reruns: "The Office" and "30 Rock." "ER," a 15-year-old drama concluding this year, clocked in for a second-place finish at a 2.7/7.

Univision remained consistent at 1.9/5 for the night. CW stayed in reruns with "Supernatural" and "Smallville," finishing with a 0.8/2 among 18-49 viewers and 1.0/3 with its 18-34 viewers.
