Mediamark Research (MRI) finds that 11.2 percent of U.S. adult households have DVRs, up from 8.6 in the fall of 2005 and 3 percent in 2004.

DVRs households record an average 11.3 shows per week, up 23 percent from last year. The number of shows actually recorded on DVRs is low relative to the volume of TV consumed. The report estimates 4 percent of all TV viewing in the U.S. is recorded or consumed through on-demand channels.

DVR owners tend to have higher levels of education and household incomes. College educated adults comprise 36.8 percent of DVR owners, compared to 25.2 percent of the U.S. adult population. Seventeen percent of DVR homes have an average household income exceeding $150,000, compared to 8 percent of the general adult population. Nearly 16 percent of DVR households own homes worth over $500,000, compared to 9 percent of the general population.

Media usage among DVR owners is also more aggressive. Adults in DVR households are 43 percent more likely to read magazines regularly; 40 percent more likely to be heavy readers of newspapers; and 81 percent more likely to use the Internet on a regular basis than non-DVR homes.

While DVR households have the ability to watch more TV, and often record two programs simultaneously; they tend to watch less TV than non-DVR households. The DVR contingent is 23 percent less likely to be heavy TV watchers.
