Week No. 20: Live + 7 Day Ratings:

Based on Nielsen's Live + 7 Day information for the week of February 1, 2010, which included the first round of data for the Season 6 of "Lost," the 6th-year ABC drama premiere picked up an additional 2.2 million viewers (12.1 million to 14.3 million) and 1.1 Adult 18-49 rating points (5.6 rating to 6.7 rating) through DVR playback from its first-reported overnight numbers. In fact in terms of actual gains and percentage gains, it was the biggest-ever increase for a "Lost" season opener through DVR playback. In the finalized numbers, "Lost" stood as the week's No. 1 scripted TV show with Adults 18-49.

During the week, ABC's "Grey's Anatomy" was once again TV's most-played-back show, while "Lost," "Modern Family" and "Private Practice" all saw substantial gains in the finalized DVR playback averages.

� ABC claimed 3 of TV's Top 8 biggest overall gainers, with each show jumping by more than 2 million viewers: "Grey's Anatomy" � No. 1 (+2.758 million), "Lost" � No. 5 (+2.207 million) and "Modern Family" � No. 8 (+2.164 million � biggest freshman gainer).

� Among Adults 18-49, ABC aired 4 of the Top 10 TV series with the biggest rating increases: "Grey's Anatomy" � No. 1 (+1.4 rating points/+31%), "Lost" � No. 4 (+1.1 rating/+20%), "Modern Family" � No. 4 (+1.1 rating/+28% - biggest freshman gainer) and "Private Practice" � No. 10 (+0.8 rating/+24%).

A note about increasing DVR penetration and year-to-year rating comparisons: Year-to-year rating comparisons based on the Live + Same Day data stream are distorted by the level of DVR penetration in the Nielsen sample, which has jumped up to 36% currently, from 30% at the same point in 2009. More viewers are watching shows on their own timetables, which may not be reflected in the overnight next day numbers. The only truly valid year-to-year comparison would be one based on the Live + 7 Day metric, once those stats are released by Nielsen.
