Update 11:25a PT: Presidents Day might have played a role with last night's results, but some of the blame can be put on the NBA All-Star Game which pulled a 4.0 adults 18-49 rating and over 9 million viewers.
FOX edged out ABC for a nightly win with adults 18-49, and ABC edged out CBS for second place. CBS of course won with total viewers.
The Amazing Race got off to a slow start with a 2.4 adults 18-49 rating, down from a 2.8 rating a year ago on February 21, 2010. For the hour, it tied with Extreme Makeover: Home Edition, though "Makeover" had a few more total viewers.
Both Desperate Housewives and Brothers & Sisters were up from last week when they were pummeled to lows by the Grammy Awards. "Housewives" was up 15% to a 3.1 adults 18-49 rating and "Brothers & Sisters" was up 12%, but still couldn't quite manage a 2.0 adults 18-49 rating, settling for a 1.9 rating. All the Fox animations were up a bit from last Sunday too, but considering there were no Grammy Awards this week, it seemed a pretty slow Sunday night.
Relatively speaking, the SNL "Backstage" special pulled impressive numbers averaging a 2.1 rating in adults 18-49 from 9p-11p and tying for the lead in 18-49 for the 10pm hour.
Both Undercover Boss and CSI: Miami were down from their last originals, 'Boss' significantly, but "Miami" only 6%,

Definitions:
Fast Affiliate Ratings: These first national ratings, including demographics, are available at approximately 11 AM (ET) the day after telecast, and are released to subscribing customers daily. These data, from the National People Meter sample, are strictly time-period information, based on the normal broadcast network feed, and include all programming on the affiliated stations, sometimes including network programming, sometimes not. The figures may include stations that did not air the entire network feed, as well as local news breaks or cutaways for local coverage or other programming. Fast Affiliate ratings are not as useful for live programs and are likely to differ significantly from the final results, because the data reflect normal broadcast feed patterns. For example, with a World Series game, Fast Affiliate Ratings would include whatever aired from 8-11PM on affiliates in the Pacific Time Zone, following the live baseball game, but not game coverage that begins at 5PM PT. The same would be true of Presidential debates as well as live award shows and breaking news reports.
Rating: Estimated percentage of the universe of TV households (or other specified group) tuned to a program in the average minute. Ratings are expressed as a percent.
Share (of Audience): The percent of households (or persons) using television who are tuned to a specific program, station or network in a specific area at a specific time. (See also, Rating, which represents tuning or viewing as a percent of the entire population being measured.)
Time Shifted Viewing – Program ratings for national sources are produced in three streams of data – Live, Live+Same Day (Live+SD) and Live+7 Day. Time shifted figures account for incremental viewing that takes place with DVRs. Live+Same Day (Live+SD) include viewing during the same broadcast day as the original telecast, with a cut-off of 3:00AM local time when meters transmit daily viewing to Nielsen for processing. Live+7 Day ratings include incremental viewing that takes place during the 7 days following a telecast.
For more information see Numbers 101 and Numbers 102.
