On March 6th, 2012, Google officially launched Google Play in order to consolidate its mobile stores and compete more effectively with Apple’s App Store. Four years later, Android has seen explosive growth in the apps department, with revenue climbing by a massive 35x in that timespan.

This week, analytics firm App Annie took a look back at the past four years to see which apps have contributed most to that astounding growth.

First up we have a list of the most downloaded Android apps of all time:

  1. Facebook
  2. WhatsApp
  3. Facebook Messenger
  4. Instagram
  5. Clean Master
  6. Skype
  7. LINE
  8. Viber
  9. Twitter
  10. Flashlight by Surpax

That’s eight social media apps in the top ten, including four owned by Facebook… which all happen to be in the top four slots. To say that Facebook has dominated Google Play would be an understatement. As for the two outliers — Clean Master promises to boost speed, save battery and protect from viruses while the flashlight app does exactly what you’d expect it to do.

The list looks a bit different when you rank by revenue:

  1. LINE
  3. LINE Manga
  4. Pandora Radio
  5. KakaoTalk
  6. GREE
  7. Pokemini
  8. Dragon Quest X Adventurer’s Convenient Outing Tool
  9. LOVOO
  10. Tinder

LINE is nearly as dominant when it comes to revenue as Facebook is when it comes to downloads. Those stickers must really be impossible to resist. A couple of free-to-play games also appear, with two dating apps to round out the list.
