 "Google sets sights on TVs, cars and watches")
Google's free Android software runs on more than three out of every four smartphones sold globally: a valuable entry point for consumers to access its money-making online services such as Web search and maps.
At its annual developers' conference on Wednesday, the company said the first cars running Android Auto software for navigation, music and messaging will hit showrooms later this year. More than 40 auto companies had signed onto its software development alliance, but Google did not say which ones will actually build Android into their cars in 2014.
Samsung and LG smartwatches running Android Wear, the version of Android tailored for wearable devices, go on sale later Wednesday.
And executives demonstrated how Android TV, reviving Google's foray into streaming video, aims to give viewers an easy interface through which to search for and display content. TV version of Android comes four years after Google's first effort to enter the living room, via Google TV, failed to catch on with consumers.
"It's a land grab," said Sameet Sinha, an analyst with investment bank B. Riley & Co. "The person who gets a platform which controls the devices could be the dominant operating system, not of just devices, it could be the operating system of your home."
"New platforms offer new opportunities for hardware sales, advertising sales, e-commerce sales, all of these," Sinha said.
