Tivo pioneered digital video recorders. But cable companies are getting into the act. “So far, 2.5 million to 2.8 million of the nation’s roughly 110 million homes have digital video recorders. But DVR’s inspire fierce loyalty from those who have them, terrify advertisers (because they can be used to skip commercials) and are seen by many media experts as the future of television. The Yankee Group estimates that in four years, almost 25 million homes will have digital video recorders and that about two-thirds of those will be DVR’s that have been integrated into satellite or cable set-top decoders.”
