CBS scored a predictable win for Thursday night with Big Brother, while ABC's Expedition Impossible ended its first-season journey in a good place during an evening heavy with reruns, according to preliminary numbers.

ABC's night began at 8 p.m. with Wipeout, which performed flat versus last week with a 1.9 rating/6 share in the adults 18-49 demographic and 6.7 million total viewers. The Expedition Impossible finale aired the following hour, jumping 15 percent versus last week with a 1.5/4 in the demographic and 5.1 million total viewers. Rookie Blue at 10 grew 8 percent for a 1.3/4 and 5.1 million total viewers. (Numbers for the Big Three networks were likely a bit inflated for the night, due to local NFL pre-season pre-emptions.)

At CBS, Big Brother at 9 had a 6 percent increase for a 3.2/9 and 8.4 million total viewers. The rest of the network's primetime roster consisted of repeats.

NBC and Fox ran repeats throughout the evening.
