There are loads of different apps available on the Play Store now, but it wasn't always the case some years ago. Now with Android having well over a million different apps available for users and still climbing on a daily basis, it's easy to find an app that can suits everyone's tastes. Some apps are also literally popular with just about everyone, and those are the ones which usually hit a point where they reach a billion installs. To be sure, reaching a billion installs is a huge milestone for any app, but it's is likely a lot easier to reach for the ones which are developed by some of the most well-known companies out there.
Take Google's Chrome for Android browser for example, which just recently reached over a billion installs. Although it's Google and it isn't the first Google app to hit this number of app installs from their library of offerings, there are a ton of browsers available on the Play Store, some of which have been around quite a lot longer than Chrome. Dolphin Browser is one such option which has been on Android nearly since the beginning. With now hitting this popularity mark, it's following up Google's Hangouts app which hit a billion installs itself just last week. Chrome is also said to mark the 12th app which has reached a billion installs, which should put into perspective just how difficult it can be to actually achieve this sort of thing.
Out of the 12 apps total which have reached a billion installs, 9 of them are developed by Google, with the other three being Facebook, Facebook's Messenger app and the now Facebook-owned Whatsapp, another popular messenger application. The other apps included are YouTube, Gmail, Maps, Play Books, and Google+ among others. It's also likely that we could be looking at street view as the next app in the Play Store to hit a billion installs. If you step back and take a look at the only apps which have reached this number, every single app comes from one of two of the biggest tech companies globally, Google and Facebook.
