Google Play is gaining market share the fastest in emerging markets like India, Vietnam and Pakistan, even if growth since 2012 has largely been driven by a relative handful of countries, including the United States and Japan. 

Four of the top-10-grossing Google Play games of all time were driven almost entirely by store revenue in Japan. Japan leads in revenue generated by six of the top-10 apps. While Facebook dominated in downloads, LINE owns the three top-grossing apps of all time, fueled primarily by revenue in Japan.

Google Play downloads grew by almost 400 percent, while  app store-related revenue has gone up by a staggering 3500 percent, according to App Annie.

 

U.S. users drove downloads for six of the top 10 apps on Google Play. On the Apple App Store, U.S. users led downloads for all of the top 10 apps.

Casual-style games were nine of the top-10 downloaded Google Play games of all time, representing approximately 40 percent of total all-time downloads and approximately 90 percent  of total all-time revenue.
