Internet technologies promise to soon take couch potatoes to worlds far beyond TiVo

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.
