While CBS's "Amazing Race: Unfinished Busines debut was nothing to be ashamed of, though it wasn't quite as powerful in the ratings as it hoped to be. Meanwhile, ABC's night rose from last week's, getting a nice boost from an awards show-free night. A two-hour behind the scenes look at the "SNL" machine couldn't keep the nostalgia afloat.

CBS wins Sunday with 10.4 million viewers and a 6.2 rating/10 share in households. ABC followed with 8.7 million (5.3/9). NBC had by 5.7 million viewers (3.5/6), and FOX had 5.2 million (2.9/5).

In the key 18-49 demo, FOX won with a 2.4, followed by ABC with 2.3, CBS with 2.2, and NBC with 1.6.
