More than a million apps have been published to Google Play to date. Initially, Google Developers had to submit their applications to the Google Play store, and many apps are still primarily sold through this official Google app marketplace. However, because Android is open source, many other companies have since been successful in creating their own app stores – for example, Amazon has built a separate app store for users of their Kindle devices, which run a version of Android. This fragmentation of the app marketplace gives more control to developers and stands in contrast to the closed, highly-curated Apple ecosystem. Even today, the application review process for Google Play is primarily intended to weed out explicit or offensive content, and it doesn’t significantly affect the time it takes to publish an app.
