Google and Intel have teamed with Sony to develop a platform called Google TV to bring the Web into the living room through a new generation of televisions and set-top boxes.

The move is an effort by Google and Intel to extend their dominance of computing to television, an arena where they have little sway. For Sony, which has struggled to retain a pricing and technological advantage in the competitive TV hardware market, the partnership is an effort to get a leg up on competitors.

The partners envision technology that will make it as easy for TV users to navigate Web applications, like the Twitter social network and the Picasa photo site, as it is to change the channel.

Some existing televisions and set-top boxes offer access to Web content, but the choice of sites is limited. Google intends to open its TV platform, which is based on its Android operating system for smartphones, to software developers. The company hopes the move will spur the same outpouring of creativity that consumers have seen in applications for cellphones.
