Aliant’s service pushes TV signals through high-speed Internet lines to desktop PCs, which have several obvious advantages over current set-top boxes. With far greater RAM, processor speeds, memory and storage, the chance that viewers will be ordering the dress Jennifer Aniston is wearing on Friends through a service like TV on my PC rather than through their digital cable or satellite set-top boxes is huge. In at least the area of interactivity, Aliant’s TV on my PC should be seen as a competitive threat to cable and satellite’s digital plans to generate iTV revenues. Cable and satellite currently rely on a two-screen interactive model. TV watchers are referred to an Internet address where they can get more information or place an order. But a customer viewing TV on my PC doesn’t have to go anywhere; they are just a click away from wherever they are being told to go or whatever they are being told they could buy. In conjunction with TV on my PC, Aliant also launched Music on my PC, where high-speed Internet subscribers can listen to commercial-free music and order online any music they hear. People viewing music videos on MuchMusic on their television won’t be able to do this so easily, even if they have signed up for web TV because it allows Internet viewing only at its most basic (CCR, Feb. 28/01). Cable companies and satellite operators cannot afford to ignore Aliant’s TV on my PC and Music on my PC because of its potential in the arena of interactivity. Of course, it may all prove a debate over naught if consumers never demand iTV in the first place.
