Note: DVR penetration is at 42%, up from 38% last year. Last fall, Live+7 audiences for original entertainment series on CBS gained over 1.8 million viewers, on average, over Live+ Same Day ratings, more than any other network. This season, we expect DVR penetration to continue to increase and, as a result, we expect DVR playback audiences to grow as well.
