The entire NBC lineup improved over last week in Thursday’s overnight ratings, TVbytheNumbers.com reports, but even so, the network remained mired in fourth place.

Fox won the night in the key 18-49 demo with a 3.4 average rating, followed closely by CBS with a 3.3. Next was ABC with a 2.4 average, and NBC clocked in with a 1.9.

Total viewers saw CBS on top with an average of 12.9 million, followed by Fox with 10.6 million, ABC with 7.1 million and NBC with 4.5 million.

A number of shows were up from a week ago, but the story notes that the World Series game last week threw things out of whack.

NBC’s lineup appeared to benefit the most: “Community” rose 21% to a 1.7 average rating in 18-49, “Parks & Recreation” was up 11% to a 2.0, “The Office” climbed 7% to a 3.1, “Whitney" rose 5% to a 2.1 and the struggling “Prime Suspect” got good news in the form of a 9% spike, to a 1.2 average.

At Fox the news was a good season premiere for “Bones” with a 3.3 average rating in the 18-49 demo, along with a 3.6 for “The X Factor’s” results show.

CBS had the night’s top show, “The Big Bang Theory,” which matched a Thursday high with a 5.1 in 18-49. “Rules of Engagement” also had a Thursday high, with a 3.7. “The Mentalist’s” 2.9 was its best in the 18-49 demo since April, and “Person of Interest” held its ground with a 2.7.

On ABC, “Grey’s Anatomy” was the star performer with a 3.5 average rating in 18-49, “Private Practice” was up a bit with a 2.6 and “Charlie’s Angels,” which is still on the air despite being canceled, squeaked out a 1.2 rating.
