Pokemon GO is continuing to add achievements to its already impressive resume and in a relatively short time span. Nintendo and Niantic's juggernaut has officially exceeded 50 million downloads (worldwide) via Google Play, which is notable for a few reasons.
First, let us talk time frame. Pokemon GO has only been available since July 5th, which is a total of 22 days on the open market (via Sensor Tower). That makes it the fastest to achieve 50 million installs on the platform. Second, Pokemon GO is still only available in 32 of the 100 markets that the App Store and Google Play inhabit.
Speaking of the App Store, when you add that to the Google Play numbers, it is estimated that Pokemon GO has been installed more than 75 million times across both services. At that rate, the competition isn't even close. It also managed to accomplish that feat without any giant marketing push, and it hasn't even been included as the featured app on either store front.
That said, the game has dominated discussion on social media and news sites just like ComicBook.com, so as of yet Nintendo and Niantic haven't really had a reason to invest much into the marketing side of things.
In comparison, Supercell's Clash Royale launched about four months ago and has great reviews. The game is still trying to amass 50 million downloads worldwide. That isn't to slight Clash Royale at all, as that is much more inline with normal game releases, but Pokemon GO has entered another stratosphere.
While all the attention should die down at some point, the game will continue to break records as it releases in new territories throughout the year.
