New DVR playback numbers show increased time-shifting by audiences, with the most popular dramas such as ABC’s "Grey’s Anatomy" and Fox’s "House" showing the most added viewing compared to premiere week ratings, reports Variety.

Comedies such as CBS’ "The Big Bang Theory" and NBC’s "The Office" also got a boost. NBC, however, benefited the least from first-week DVR viewing, with relatively little playback of "Sunday Night Football," and "The Jay Leno Show."
