Google Inc. wants to bring the Internet to your television screen. The Internet giant unveiled a new platform called Google TV that it says “will change the future of television” during the company’s developer conference Thursday in San Francisco. Google is putting its Android software and Chrome Web browser on television and other home entertainment devices in an attempt to succeed where others have struggled: in merging television and the Internet. Google TV will be available on television sets, Blu-ray players and companion set-top boxes through partnerships with Intel Corp. and Sony Corp. Special “input devices” will include a keyboard and remote-control-type pointing device. The first devices will be available in the fall in time for the holiday shopping season.
