Due to the nature of live programming the ratings for CBS (NCAA Basketball) are approximate and subject to more than the typical adjustments in the final numbers. See below for more information on these Fast Affiliate Ratings.

American Idol was down sharply from last Thursday, but Fox still easily topped the broadcast adults 18-49 ratings on Thursday. In what’s no longer an unusual event, Univision again topped NBC in adults 18-49.

American Idol’s season low 5.6 adults 18-49 rating was down 16% vs. last Thursday. Adults 18-49 viewing was down 12.4% vs. last Thursday, more Daylight Saving Time? Interestingly, Bones‘ 3.4 rating rose 6% vs. last week. Note: Any Idol overrun would likely cause Idol to be adjusted up, and Bones adjusted down in the final ratings available later today.

On NBC, the just renewed Community slipped a tenth of a point vs. its last new episode in February to a season low 1.7 adults 18-49 rating. Perfect Couples 1.2 rating was a season/series low down 14% from its last new episode. After an Office repeat, the also renewed Parks & Recreation tumbled 25% vs. its last new episode to a 1.8 rating, a series low. Only Outsourced was even with its last new episode, although at a series/season low 1.4 rating.

ABC’s Wipeout scored a 2.0 adults 18-49 rating at 8pm, down 9% vs. 2/24. In a special 9pm timeslot, Private Practice’s 1.9 rating was a series low, down 17% vs. its last new episode at 10pm.

Although we need to wait until the final ratings are in for comparisons, CBS’ NCAA Basketball ratings will certainly be lower than last season, since beginning this year, TNT, TBS and truTV were all broadcasting games in addition to CBS.

Late-night results are below the primetime data.

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 which are currently in approximately 24.4% of all U.S. TV households. 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.
