Editor's Note: DVR penetration is at 46%, up from 42% last season. Last fall, Live+7 audiences for original entertainment series on CBS averaged more than a +1.4 million viewer gain over Live+ Same Day ratings, more than any other network. This season, we expect DVR usage to continue to expand, increasing DVR playback deliveries.
