NBC Universal is running an unprecedented 3,600 hours of Olympics coverage on television and the Internet, most of it live online, letting fans track their favorite sports in a way not possible even if they'd gone to Beijing.

Excited by the prospects, I set my alarm for 4:45 a.m. on Sunday to catch cycling, handball, archery and rowing events on NBCOlympics.com as they happen half a world away in China -- 12 hours ahead of New York.

The set-top box, a necessary appendage for millions of cable televisions for decades, is moving toward extinction.

A leading television manufacturer, Sony Electronics Inc., and the National Cable and Telecommunications Association said Tuesday they signed an agreement that will allow viewers to rid themselves of set-top boxes yet still receive advanced "two-way" cable services, such as pay-per-view movies.

In most cases, cable viewers also could dispose of another remote control since they could use their TV's control rather than one tied to the set-top box.
