'30 Rock' Ratings Down in Return … and 'Grey's' Continues to Slide THR

The ratings for Thursday night were a mixed bag, starting with "30 Rock's" fourth-season premiere, which were down  27% from last year in the adult demo, according to The Hollywood Reporter.

"Rock's" 3.0 Nielsen rating among adults 18-49 was off 25% from the show preceding it, "The Office." Meanwhile, on ABC, "Grey's Anatomy" was the top-rated network show, and helped ABC to win the night, but the show was off 9% from last week and that makes four weeks in a row of decline. CBS came in second overall, with "Survivor" (3.5), "CSI" (3.6) and "Mentalist" (3.4) all up 3%.

For NBC, at 8 p.m., "Community" and "Parks & Recreation" both had a 2.0, while at 9 p.m. "The Office" posted a 4.0, down 17% from last week's one-hour Pam-Jim wedding episode.
