Google is reportedly previewing a significant update to its Google TV platform, which is referred to by the monicker "Fishtank." The Google TV 2.0 private beta, which is said to be limited to just 50 developers, is built on Android 3.1 reworked for television presentation. The UI includes a Clock app, the Live TV feature, and a Chrome build that appears to be a closer match to the desktop utility rather than the smartphone browser.
