NEW YORK, Sept. 30 (UPI) -- After a first week that had "CSI" behind in U.S. ratings to ABC's "Grey's Anatomy," the Las Vegas crime drama topped its medical opponent this week.
The CBS series, which had long been the king of Thursday night ratings, fell to the Seattle-based medical drama during the first week of the new fall TV season, but this week regained the night's ratings lead by nearly 200,000 viewers, said the New York Daily News.
With its 23.49 million average viewers, an increase of 910,000 from its debut according to Nielsen Media Research, "CSI" beat out "Anatomy," which lost 2.1 million viewers from its first week to fall to average of 23.3 million.
CBS also scored big with its new drama "Shark," starring James Woods, which toppled perennial NBC mainstay "ER" by 400,000 viewers.
The paper said that while CBS did take home this week's Thursday night crown based on the success of "CSI," "Anatomy" did win the battle in terms of the key advertising demographic of viewers aged 18 to 49.
