App store
Apple released iPhone OS 2.0 in July 2008 for the iPhone, together with the App Store, officially introducing third-party app development and distribution to the platform. The service allows users to purchase and download new apps for their device through either the App Store on the device, or through the iTunes Store on the iTunes desktop software. While Apple has been criticized by some for how it operates the App Store, it has been a major financial success for the company. The popularity of Apple's App Store led to the rise of the generic term "app store", as well as the introduction of equivalent marketplaces by competing mobile operating systems: the Android Market (later renamed to Google Play) launched alongside the release of the first Android smartphone (the HTC Dream) in September 2008, BlackBerry's App World launched in April 2009, as well as Nokia's Ovi Store and Microsoft's Windows Marketplace for Mobile both launching that year too.
