Ratings: Grey's and CSI, the eternal dance

While all the white-haired viewers gasp in their rocking chairs at the CBS adventures of Gil Grissom and his CSI friends, the cool new hotties of Grace Whatever make love and heal hearts on ABC's Grey's Anatomy.

And viewers are taking notice.

Grey's Anatomy scored a 10.7 rating in adults 18-49, with 25.6 million viewers overall, outdistancing CBS' also solid CSI, in with a 7.2 and 22.5 million viewers. The third season medical drama has been overtaking the aging crime drama for most of the season.

Over at NBC, the wonderfulness that we humans call Alec Baldwin helped 30 Rock earn its meager weekly take of a 2.4 rating and 5.0 million viewers overall. Idea: Alec Baldwin as a wacky detective who dons various costumes, Rockford Files crossed with Fletch.

At 8 p.m., CBS took a 5.6 for the new Survivor. ABC earned a 4.5 for that crazy fashion nutso Ugly Betty, and NBC scored 4.2 average for My Name is Earl and The Office. Fox took a combined 2.3 for Til Death and The War at Home, and CW earned a 2.0 for Smallville.

At 9 p.m., ABC snared a sweet little 10.7 for Grey’s Anatomy, with CBS gunning a 7.2 for CSI. NBC came in with a combined 2.7 for Scrubs and 30 Rock. Fox took a 1.6 for the second-to-last episode of The O.C. CW scored a 1.4 for Supernatural.

At 10 p.m., NBC led with a 4.6 for ER. CBS Shark bit off a James Woods-sized 4.3. ABC stormed a 4.1 for Men In Trees.

Overall, ABC took a 6.4 rating/16 share, with 16.8 million total average viewers; CBS, 5.7/14, 18.0 million; NBC, 3.9/10, 8.7 million; Fox, 1.9/5, 4.4 million; CW, 1.7/4, 4.1 million.
