DVR users' TV viewing generally rose with age. Respondents under 30 watched an average of 3.7 hours daily, while middle-aged TV viewers had the TV on for as long as 5.4 hours.

The number of DVR households in the US will pass 30 million in 2008 and climb to 48 million in 2012. At that point more than four out of every 10 households will have a DVR.

The recorders are definitely linked with increased TV viewing: The average DVR owner surveyed watched 4.7 hours of television per day—over 1 hour per day more than the 3.7 hours viewed by adults surveyed in June 2008 by The Media Audit.
