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.
