CBS' "The Amazing Race" got a bit of a boost this week over last Sunday's numbers, while ABC's "Once Upon a Time" dipped with total number of viewers -- most likely due to the NCAA basketball tournament running over by almost an hour and bumping shows from their time slots. However, the fairy-tale show did manage to pick up some more 18-49-year-old viewers this week, winning the demographic for the time slot.

Also down a bit was NBC's "The Celebrity Apprentice," though it did tie with "GCB" -- also down this week -- for most viewers in the 18-49 demo for the 10 p.m. hour.

CBS got the top spot among total viewers for the evening, averaging 9.7 million and a 6.2 rating/10 share in households for the night. ABC (7.5 million, 4.6/8) came in second ahead of NBC (6.4 million, 4.2/7) and FOX (4.3 million, 2.4/4).

In the adults 18-49 demographic, CBS won out this week with a 2.3 rating. ABC was a close second with a 2.2, while FOX got a 2.0 and NBC finished with a 1.4.
