Google Play (formerly Android Market) is a digital distribution and multimedia content delivery service operated and developed by Google. It serves as the official app store for certified devices running on the Android operating system and its derivatives as well as Chrome OS, allowing users to browse and download applications developed with the Android software development kit (SDK) and published through Google. Google Play also serves as a digital media store, offering music, books, movies, and television programs. Content that has been purchased on Google Play Movies & TV and Google Play Books can be accessed on a web browser, and through the Android and iOS apps.
Applications are available through Google Play either free of charge or at a cost. They can be downloaded directly on an Android device through the proprietary Play Store mobile app or by deploying the application to a device from the Google Play website. Applications utilizing hardware capabilities of a device can be targeted to users of devices with specific hardware components, such as a motion sensor (for motion-dependent games) or a front-facing camera (for online video calling). The Google Play store had over 82 billion app downloads in 2016 and reached over 3.5 million apps published in 2017, while after a purge of apps is back to over 3 million. It has been the subject of multiple issues concerning security, in which malicious software has been approved and uploaded to the store and downloaded by users, with varying degrees of severity.
On Google Play, free applications are available worldwide, while paid applications are available in 129 countries. Applications can be installed from the device or the Google Play website. According to Google there were over 450,000 titles available as of March 2012. Google Play can update the applications the user selects automatically, or users can update then on a per-case basis or update all applications at once.
Google Play filters the list of applications to those compatible with the user's device. In addition, users may face further restrictions to choice of applications where developers have tied-in their applications to particular carriers or countries for business reasons. Carriers can also ban certain applications, for example tethering applications.
Some carriers offer direct carrier billing for Android Market application purchases. Purchases of unwanted applications can be refunded within 15 minutes of the time of download. There is no requirement that Android applications be acquired from Android Market. Users may download Android applications from a developer's website or through a third-party alternative to Android Market.
Developers in 29 countries may distribute applications on Google Play. However developers pay $25 for registration to distribute on the Android Market. Application developers receive 70 percent of the application price, with the remaining 30 percent distributed among carriers and payment processors. Google itself does not take a percentage. Revenue earned from the Android Market is paid to developers via Google Checkout merchant accounts, or via Google AdSense accounts in some countries.
On 17 March 2009, about 2,300 applications were available in Android Market, according to T-Mobile chief technical officer Cole Brodman. On 10 May 2011, during the Google I/O, Google announced that Android Market had 200,000 applications listed and 4.5 billion applications installed.

Google announced the Android Market on August 28 2008, and made it available to users on October 22 2008. They introduced support for paid applications on February 13 2009 for US and UK developers, with additional support for 29 countries on September 30 2010.
In December 2010, Google added content filtering to Android Market and reduced the purchase refund window from 24–48 hours to 15 minutes.
In February 2011, Google introduced a web client that provides access to Android Market via PC. Applications requested through the Android Market web page are downloaded and installed on a registered Android device.
In May 2011, Google added new application lists to Android Market, including Top Grossing applications, Top Developers, Trending applications, and Editors Recommendations. Google's Eric Chu said the goal of this change was to expose users to as many applications as possible.
In July 2011, Google introduced a redesigned interface with a focus on featured content, more search filters, and (in the US) book sales and movie rentals.
In September 2011, the Motorola Xoom tablet received an update that brought the redesigned Android Market to an Android 3.x Honeycomb based device.
In November 2011, Google added a music store to the Android Market.
In March 2012, the maximum allowed size of an application's APK file was also increased from 50MB to allow two additional files for a maximum of 50MB for the APK and two additional files of 2GB each, totalling 4050MB/4.05GB.
On 6 March 2012, the Android Market was re-branded as Google Play.
The Google Play application is not open source. Only Android devices that comply with Google's compatibility requirements may install and access Google's closed-source Google Play application, subject to entering into a free-of-charge  licensing agreement with Google. In the past, these requirements had included 3G or 4G cellular data connectivity, ruling out Android-powered devices comparable to Apple's iPod touch, but this requirement had been loosened by the 2011 release of the Samsung Galaxy Player.
Android Market applications are self-contained Android Package files. The Android Market does not install applications; it asks the device's Package Manager Service to install them. The package manager becomes visible if the user downloads an APK file directly into their device. Applications are installed to the phone's internal storage, and under certain conditions may be installed to the device's external storage card.
