New York Times:
NBC continued to steamroller its competitors on Monday, with its coverage of the 2008 Beijing Olympics attracting an average of 30 million viewers during prime time, according to
CBS, which was runner-up with its line-up of repeats, saw its ratings drop nearly 20 percent from a week ago among adults 18 to 49. CBS fared best at 9 p.m. with "Two and a Half Men" (8.1 million) and moderately well at 10 p.m. with "CSI: Miami" (6.5 million). At 9:30 p.m., "The New Adventures of Old Christine" drew 5.8 million viewers, while CBS's 8 p.m. comedies, "The Big Bang Theory" and "How I Met Your Mother," struggled to attract 5 million.
In one fairly dramatic statistic, no other network was able to attract more than 3 million viewers in any given hour.
