Google Play is a digital distribution service, including a digital media store, the Google Play Store (originally the Android Market), operated and developed by Google. It serves as the official app store for the Android operating system, allowing users to browse and download applications developed with the Android SDK and published through Google. Google Play also serves as a digital media store, offering music, magazines, books, movies, and television programs. It previously offered Google hardware devices for purchase until the introduction of a separate online hardware retailer.
Applications are available through Google Play either free of charge or at a cost. They can be downloaded directly to an Android or Google TV device through the Play Store mobile app, or by deploying the application to a device from the Google Play website.Applications exploiting hardware capabilities of a device can be targeted to suitable users by requisite hardware attribute, such as a motion sensor (for motion-dependent games) or a front-facing camera (for online video calling).
