Google TV integrates Google’s Android operating system and the Linux version of Google Chrome browser to create "a new experience for television". - Wikipedia
Google TV combines Android with unique TV applications (Google Play, Chrome, TV search, and others) to open the living room to the web, making all television content more relevant and engaging.
With Honeycomb (Android 3.1), this is an opportunity to create an application for multiple devices. With minimal adjustment, you can build an app for Google TV as well as for Android tablets and phones.
Google TV has been surpassed by Android TV
