House-hunting from your couch

Digital cable may be trampling the strength of TV advertising, but it has given birth to new marketing opportunities for industries that have never found commercials beneficial. Comcast has channels dedicated to shopping, exercising, and now real estate. Those who have the urge to buy a new house are not restricted by showing hours nor are they dissatisfied with black-and-white innate images. Comcast enables house hunters to look at what they want, when they want, and more importantly, without leaving the house. With the click of the remote, buyers have access to hundreds of houses that can be viewed on television. This saves them a substantial amount of time and money by only going to physically see a potential home after preliminary approval.
