Google Play, formerly known as the Android Market, is the official app store for Android smartphones and tablets. Google makes software applications, music, movies and books available for purchase and download through the store.
The Google Play store, which comes pre-installed on Android devices, allows users to purchase, download and install applications from Google and third-party developers. Google Play is the only way to download and install applications on Android devices without changing the device's application setting to "allow the installation of non-market applications."
To combat the spread of malware through the Google Play store, Google introduced Bouncer in 2012, which scans apps for threats before making them available for download.
