Bird Monkey SWF
Best originally limited to presenting vector-based objects and images in a simple sequential manner, the format in its later versions allows audio (since Flash 3), video (since Flash 6) and many different possible forms of interaction with the end user. Once created, SWF files can be played by the Adobe Flash Player, working either as a browser plugin or as a standalone player. SWF files can also be encapsulated with the player, creating a self-running SWF movie called a "projector".
Adobe makes available plugins, such as Adobe Flash Player and Adobe Integrated Runtime, to play SWF files in web browsers on many desktop operating systems, including Microsoft Windows, Apple Mac OS X, and Linux on the x86 architecture. As of 2007 intensive development had taken place on Gnash, a free-software implementation of a SWF player. Another FOSS implementation is Swfdec.
Based on an independent study conducted by Millward Brown, over 99% of Web users now have an SWF plugin installed, with around 90% having the latest version of the Flash Player.[
