This is up from the 500 million figure that was announced back in September. Pokemon Go was the most-download app on iTunes for all of 2016.
Niantic also confirmed that people have now walked around 5.4 billion miles in search of Pokemon, which is almost the distance to Pluto, apparently.
Pokemon Go is a free-to-play game that is available now on iOS and Android devices, as well as Apple Watch. The game makes its money from microtransactions–and those have been a huge hit.
In other news, Pokemon Go recently added 80 new creatures, while a special event to celebrate Pokemon Day is going on right now.
