The first iteration of Google TV fell flat. It was, at its core, a good idea that was marred by poor execution and mismanagement. Now the search giant is ready to give it another go.

Starting Sunday, Google will roll out a software update to existing owners that’s meant to serve as a reboot of the service. The update will bring a new interface as well as selected apps from the Android Marketplace – but it will also bring a lot of baggage and hurdles from the existing service (most notably the lack of any support from the major networks).
