The Nielsen Company today released the first look at the most "timeshifted" broadcast network television programs in the U.S., with FOX's House and ABC's Lost showing the most lift in audience due to playback with a Digital Video Recorder (DVR) within seven days of its initial airing.

For the week of April 2 - April 8, the most recent week for which ratings for seven-day playback are available, House pulled in an additional 2.74 million DVR viewers after its April 3rd airing, while Lost pulled in an additional 2.47 million viewers after its April 4th episode. The April 3rd episode of American Idol on FOX was third with 2.45 million viewers.
