Google Assistant and Google Home had a big year in 2017, and today Google let us know just how big it was.

Google Assistant is now on more than 400 million devices. That includes Google Home devices and Android phones and tablets as well as iPhones, headphones, TVs, smartwatches, and more. Google's Assistant is available in 12 countries and 8 languages.

When it comes to Google Home, Google says that it sold more than one Google Home device every second since the Google Home Mini began shipping to consumers in October. Over the past year, Google touts that it's sold "tens of millions" of Google Home devices.

Finally, Google says that its Assistant can control more than 1,500 smart home devices from more than 225 brands.

Google Home has long be a solid device, but at more than $100, its price can be a bit prohibitive for folks interested in the smart speaker market. That's where Google Home Mini comes in, giving these people a $50 device with which to dip their feet into the smart speaker market. With the news that Google has sold more than one Home device every second since the Mini's launch in October, it sounds like the Mini has served its purpose well.

Do you have a Google Home device? If so, which one?
