Best answer: Google TV is a new interface for Android TV that is powered by Google's machine learning, Google Assistant and the Google Knowledge Graph. It also reorganizes your content to help make it easier for you to find what you want to work.

Google TV is the next stage of Android TV
To start things off, Google TV is not replacing Android TV, because Google TV is not an operating system. Google TV is a new interface built on top of Android TV's operating system. Rather than your home screen being dominated by apps that you have to dig through separately, the new home screen interface on Google TV is centered around content first and foremost.
Google's Shalini Govilpai explained:
Google Assistant is front and center, and you'll likely be using the Google Assistant button on your Android TV — or for right now, the Chromecast with Google TV — a lot to summon up something to watch. Google Assistant and the Knowledge Graph team up to give you the exactly what you ask for when you ask Assistant to "find romance movies" or "show me sci-fi TV shows", whether the shows are on Netflix, Disney+, HBO Max, or other services.
When you search for shows on your phone or TV, you'll also be able to add them to your Watchlist so you can easily access them once you get back to the big screen. Google TV also has better integration for Live TV services, starting with YouTube TV right now and more subscriptions next year.
How is Google TV different from Android TV?
Google TV is a new software interface that sits on top of the Android TV operating system, so any TV or set-top box running Google TV is really running Google TV on top of Android TV. This also means that everything running Android TV right now might get upgraded to Google TV
What devices are getting Google TV?
Right now, Google TV is launching on the new Chromecast with Google TV, but Google has confirmed that other Android TVs and Android TV boxes will be getting Google TV starting in 2021. For right now, the only TVs we know are slated for the update are Sony Android TVs, but even then we're not sure which exact models are included.
As far as Android TV boxes, like the NVIDIA Shield TV, we have no clue when they might receive Google TV, but particularly in the case of the Shield TV, don't expect it anytime soon. NVIDIA is very hands-on when it comes to how its set-top box performs for its users, and it won't go ahead with a major interface overhaul like this before it is abundantly clear that this new UI is really better for its users compared to the current Leanback interface.
You'll be able to play with at least part of Google TV very soon, though. The Google Play Movies & TV app is being updated to become the Google TV app and will serve as a place for you to browse for something to watch, purchase movies and TV shows, and moderate your Watchlist.
