The Google Assistant is rolling out to one more form factor, as Google announced today that Android TV is finally getting its flagship voice command system.

For now, it's only on one device, the Nvidia Shield TV, but Google has said it's also coming to the Sony Bravia TV line in "the coming months." If you're wondering why the service isn't debuting on a Google-made Android TV device, it's because one doesn't exist. Since the end of the Nexus Player's run in 2016, Google hasn't offered a first-party Android TV device.

Voice commands are handled from the remote, which has a microphone built in. Users can either press the mic button and issue a command or just say "OK Google" while the box is on. On Android TV, the Google Assistant specializes in navigation and content searching. You can ask it to play shows by name, and as long as you're subscribed to the right content providers, the shows will just play. There are general remote control commands like "pause" and "unpause," and you also get access to the full suite of other Google Assistant commands, like controlling smart home devices (great for turning off the lights before a movie), asking questions, and accessing third-party voice apps.

It's clear that Google's goal is to make the Google Assistant available on as many platforms as possible, and at almost a year into this initiative, it's making good progress. The Google Assistant is on Android phones , tablets, watches, and now TVs. It's on iOS devices , too. The Assistant has a purpose-built smart speaker in Google Home , and soon we'll see several other smart speakers from third parties . It has also recently shown up on headphones . There are still some gaps in Google's Assistant rollout, though. It's currently not available on desktop computers, Chrome OS, or Android Auto, but we know there are plans for the latter two.

Nvidia Shield owners in the US should be able to download the update "starting today."
