But even if the techno-chaos of that futuristic fantasy mini-series is far off, some consumers may indeed notice that their personal relationships with their TVs, telephones and computers will be entering a new and deeper phase within a year or two.

Some cable companies are also testing other interactive models that allow viewers to choose their own news or select camera angles for sporting events.
