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. Apps requested through the Android Market web page are downloaded and installed on a registered Android device.

In May 2011 Google added new app lists to Android Market, including "Top Grossing" apps, "Top Developers", "Trending" apps, and "Editors Recommendations". Google's Eric Chu said the goal of this change was to expose users to as many apps 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.

Device compatibility

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 app, subject to entering into a free-of-charge[59] licensing agreement with Google.[60] In the past, these requirements had included 3G or 4G cellular data connectivity,[61] 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 devices's PackageManagerService 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 devices's external storage card.
