  4. DVRs Shift Viewing Habits, and Ratingsby Gary Levin, USA TODAY June 11, 2012 The increasing usage of digital video recorders, which easily allow viewers to postpone watching their favorite shows, has vastly complicated the math of TV ratings, new Nielsen data show. And it explains how ABC's Modern Family ultimately eclipsed Fox's American Idol among key young-adult audiences. Among viewers ages 18 to 49, the comedy jumped 48% when factoring in delayed viewing, while Idol's performance show gained just 17%. But viewers rarely delay reality shows, news, awards telecasts and sports programming by more than a day. Sitcoms and dramas are most prone to procrastination, accounting for 29 of the top 30 gainers. "DVRs continue to play a more important role" in overall viewing, says ABC research chief Charles Kennedy … “What's suffering at the hands of the DVR is old-fashioned channel surfing.”
