Google Play is the official store for Android media, including apps, games, and e-books. You can download content directly to an Android device using the Play Store app, or push content to a device from the Google Play website.
Introducing Google Play – What is it?
The Google Play Store is home to millions of apps and games. Some apps take advantage of your device’s hardware capabilities, such as motion sensors (for motion-based games) or a front-facing camera (for online video calls).
Google Play Pass is a subscription service that gives you unlimited access to hundreds of games in the Google Play Store.
The Books section of Google Play is an e-book distribution service where you can read or listen to e-books and audiobooks on your Android device. There are currently over five million e-book listings.
