Four of the five broadcast networks had new programming Thursday, but none of them emerged as a clear winner. "Survivor: Samoa" helped CBS win the night, but the show, now in its 19th cycle, debuted to some of its lowest numbers ever.

CBS led the night overall with 9.7 million viewers and a 6.1 rating/10 share. FOX (9 million, 5.4/9) came in second, ahead of NBC (7.3 million, 4.5/8). ABC, which was still in rerun mode, drew 4.4 million viewers and a 3.1/5. The CW brought up the rear with 3.3 million viewers and a 2.2/4.

FOX won the adults 18-49 demographic with a 3.0 rating, narrowly beating NBC's 2.9. CBS took third with a 2.5, followed by The CW, 1.4, and ABC, 1.3.
