Ratings for the second episode of ABC's 'V' took a tumble Tuesday. About 10.6 million viewers tuned in to the remake of the 1980s classic, marking a 24 percent drop from the premiere, which landed almost 14 million viewers. In the 18-49 demographic, 'V' averaged a 3.7 rating, a 26 percent drop from week one. (Each rating in that category represents 1.3 million people.) The big winner of the night was CBS, which was powered by 'NCIS' and its spinoff, 'NCIS: Los Angeles.' NBC's lone bright spot, appropriately enough, continued to be 'The Biggest Loser,' which won the 9-10 p.m. (ET/PT) hour in the 18-49 demographic with a 4.1 rating. Overall, CBS averaged 16.4 million viewers and a 3.5 rating in the 18-49 demographic. ABC was second with averages of 11.9 million viewers and a 3.2 rating in 18-49. NBC averaged 8.3 million viewers and a 3.1 rating while Fox averaged 5.7 million and a 3.5 rating in 18-49.
