Among adults 18-49, NBC averaged a 1.5 rating, topping the 1.2 rating for ABC and CBS' 1.0 rating. FOX's 0.9 rating and the 0.8 rating for The CW followed in the all-important demographic.
Overall, NBC averaged an estimated 6.84 million viewers and a 4.6 rating/8 share. CBS moved up to second with a 3.3/6, with ABC's 2.6/5 taking third. FOX's 1.9/4 was fourth, with The CW's 1.2/2 trailing.
NBC's "Who Do You Think You Are?" (featuring Susan Sarandon) was first in the 8 p.m. hour with a 4.2/8 and a 1.3 demo rating. CBS' repeat of "Ghost Whisperer" was second with a 3.0/6, beating the 2.2/4 for ABC's "Wife Swap." A repeat of "House" on FOX finished fourth overall, beating the 1.4/3 for "Smallville," which was up for last week, averaging 2.235 million viewers and finishing fourth in the demo with a 1.0 rating.
"Dateline NBC" did a 4.5/8 and a 1.4 demo rating in the 9 p.m. hour for NBC. CBS' "Medium" repeat was second. The season finale of ABC's "Jamie Oliver's Food Revolution" had a 2.5/4 and finished second in the demo. FOX's encore of Tuesday's "Glee" had a 1.8/3 for fourth. The CW stayed fifth with an "America's Next Top Model" repeat.
In the 10 p.m. hour, NBC's "Dateline" improved to a 5.0/9 and a 1.7 rating in the demo. CBS' "Miami Medical" was second with a 4.0/7, with its audience falling to just over 6 million and its demo rating falling to a 1.0 rating. The CBS freshman drama has declined in viewers and the demo every week since its premiere. Third place overall went to ABC's "20/20," with a 3.0/5, though it still topped "Miami Medical" in the demo.
