Pokemon Go has been downloaded over 500m times

"Between hordes of people running all over the place in chase of wild Pokémon, various car accidents, and celebrities getting in on the action, you're likely aware that "Pokémon Go" is ridiculously popular.
We didn't know exactly how popular the game was until Wednesday, however, when the game's creator revealed that the game has been downloaded over 500 million times.
For some context, "Pokémon Go" quickly leapt past competitors to become the fastest downloaded app of all time after it launched in early July 2016. The game was the first to hit 10 million in the shortest amount of time, and it grew far beyond that soon after. Its vast popularity has since plateaued, with the game hovering around 30-40 million monthly active users (MAUs) — that's still really impressive, but the white hot excitement has cooled somewhat in the past month or two."
