ABC's Grey's Anatomy took back its dominant lead over CBS' CSI: Crime Scene Investigation, almost doubling its adult 18-49 rating - a Nielsen 9.5 rating / 23 share over CSI's 5.0/12. That said, CBS put CSI into rerun mode, while Grey's featured the new "Don't Stand So Close to Me."
For the first time, NBC was able to show off its new four-show Thursday comedy block: My Name is Earl, The Office, Scrubs, and 30 Rock. Rock, the struggling rookie show, was able to make slight gains to a 2.7/7, rising above its season average.
This put NBC into a tie for the night with CBS, with a 4.4 rating. CBS did a smidge better in terms of share, grabbing an 11.2 number.
NBC continued to dominate the 10 p.m. time period, with ER posting 5.8/15 numbers. That bested Men in Trees, the low-rated Anne Heche-starring drama, which soared to new heights sitting behind the Grey's Anatomy audience, with a 3.8/10. Trees had been a poor player on Friday nights.
Fox, however, continues to suffer on Thursday, finishing well behind the other three networks with a 1.8/4 number for the night. A double run of Fox's first-year comedy 'Til Death posted a slightly better 2.0/5 rating and share numbers among 18-49 viewers, while The O.C. continued its ratings-challenged life this season with a 1.6/4.
