Next: TV Meets IP
Internet technologies promise to soon take couch potatoes to worlds far beyond TiVo. Even phone companies could benefit big-time

Just a few years ago, the fine art of watching TV seemed unlikely to change much. You watched programs when the networks told you to watch them. Maybe you taped them on a videocassette recorder. Either way, your choices were limited. Then along came the TiVo (TIVO ) digital video recorder, which as its 2 million loyal customers will tell you, added more than a little convenience to the coach potato's world.

Turns out, TiVo was just the start. A new wave of TV-related innovation called IP-TV is just starting to reach consumers. Just as the service known as voice over Internet protocol is poised to revolutionize the phone business by offering a low-cost Internet alternative to traditional phone service, IP-TV could bring Internet-style interactivity and flexibility to your TV set.

It won't happen overnight, of course. But over the next decade, the long-hyped notion of "video-on-demand" could become commonplace, allowing consumers to watch what they want, when they want to. They'll be able to control their IP-TV service remotely through a PC or a cell phone. And they'll be able to personalize their content, whether they want to watch the local high school football game or home movies.
