Several initiatives exist both from mobile vendor and mobile operators around the world. Application developers can propose and publish their applications on the stores, being rewarded by a revenue sharing of the selling price. An example is Apple's App Store, where only approved applications may be distributed and run on iOS devices (otherwise known as a walled garden). There are approximately 7,000,000 iOS Applications. Google's Android Market (now known as the "Play Store") has a large number of apps running on devices with Android OS. HP / Palm, Inc have also created the Palm App Catalog where HP / Palm, Inc webOS device users can download applications directly from the device or send a link to the application via a web distribution method. Mobile operators such as Telefonica Group and Telecom Italia have launched cross-platform application stores for their subscribers. Additionally, mobile phone manufacturers such as Nokia has launched Ovi app store for Nokia smartphones. Some independent companies, namely Amazon Appstore, Aptoide and GetJar, have created their own third-party platforms to reach more users in different locations. The Windows Phone Marketplace had more than 100,000+ apps available as of 7-11-2012.
