CBS' move of "The Big Bang Theory" paid off handsomely Thursday, as the season premiere dominated its time period and helped give new comedy "$#*! My Dad Says" good numbers as well.

Elsewhere, NBC's new comedy "Outsourced" did a decent job holding its "Office" lead-in, while ABC's new drama "My Generation" had a soft opening. Veterans "CSI" and "Grey's Anatomy" remained at the top of the 9 o'clock hour -- although a guest appearance by Justin Bieber didn't seem to make "CSI's" audience much younger.

CBS led the night's overall ratings by a wide margin with 14.4 million viewers and an 8.8 rating/15 share among households. ABC (9.4 million, 6.2/10) finished second, ahead of the 7.8 million viewers and 4.7/8 for FOX. NBC (5.7 million, 3.5/6) came in fourth, and The CW (3.4 million, 2.1/3) trailed.

CBS also won the adults 18-49 demographic with a 3.7 rating. ABC was not far behind with a 3.4, while NBC took third with a 2.6. FOX averaged 2.4 and The CW 1.3.
