A note about increasing DVR penetration and year-to-year rating comparisons: Year-to-year rating trends based on the Live + Same Day data stream may be somewhat distorted by the level of DVR penetration in the Nielsen sample, which has jumped from 18% at the same point in 2006-07, up to 26% currently. 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.
