You can bet that consumers will like this. The New York Times reports that Time Warner Cable is preparing to launch a DVR service called Look Back at no charge to its cable subscribers. There is a catch, of course, but one that TV station owners and networks will like. There is no fast-forward function, so no ad zapping. Cable viewers will be able to time-shift TV viewing, but only on the same day as the original broadcast. The Times says Time Warner Cable will debut the service this October in South Carolina and gradually roll it out to other markets nationwide.
