The Fox TV network, which already was expected to dominate the ratings this month with the return of American Idol, absolutely crushed the opposition Sunday night with the primetime airing of the NFC championship game between the New York Giants and the Green Bay Packers. According to preliminary Nielsen results the game drew an enormous 26.3 rating and a 39 share, translating to about 49 million viewers -- peaking to a 27.5/39 (50 million viewers) in the 9:00 p.m. hour. Among adults 18-49, the results were even more lopsided, with Fox drawing an 18.6 rating and ABC finishing far behind in second with a 2.8. CBS was in third place with a 2.0 and NBC in fourth with a 1.2.
