Well, mostly not TiVos, but a according to the NDS DVR Report (and NDS is apparently a manufacture of DVR technology) 79 percent of one thousand people surveyed reported that the digital video recorder technology has improved their relationships.
NDS reports that among technological household items, DVR came in second only to mobile phone technology. Among (what the study deems) non technological items, DVR was beaten out only by the washing machine in microwave oven.
Although NDS has skin in the game, I don't really doubt the results among DVR households. But I also think we shouldn't get ahead of ourselves just yet since Nielsen estimates DVRs are only in 24.4% of television homes in the U.S. While services like DVR have changed my viewing habits for 10 years now, uptake has not been swift. One can't help but wonder if at the end of the day, many people just like to plop down on the couch and channel surf rather than be their own programming executive.
