DVR owners watch less TV

Market research cited in the New York Times suggests adults in households with digital video recorders (DVR) watch less television than their counterparts in households without. In our house it is true without a doubt. Since 2002 when we got a pair of TiVo DVR's our TV viewing has continued to decline. Prior to TiVo it was common to leave the boob tube on all evening with some educational show... it had to be educational or it wouldn't have been on The Learning Channel, right?
