Adobe designed Adobe AIR, a cross platform environment, to run applications which use Adobe Flash, Apache Flex, HTML and Ajax. These applications can be run on desktop computers or mobile devices, like smartphones and tablets. Adobe AIR supports applications running on Windows, Mac OS and Linux, as well as Android, Blackberry Tablet OS and iOS. To utilize the features provided in Adobe AIR, flash applications must be built for Adobe AIR specifically. In the picture to the right, is an example of Pandora running on the desktop using Adobe AIR.
Adobe AIR itself uses Adobe Flash Player as a runtime environment and the programming language used to design it is ActionScript 3. The first release of Adobe AIR, originally called Apollo, was on March 19, 2007 as a public preview release. It was renamed to AIR on June 10, 2007. The first official release of Adobe Air, version 1.0, was on February 25, 2008. Version 3.3 is the latest version, as of June 5, 2012.
