Adobe Flash is the industry-standard application for creating animation and playing video on Web sites. It is fairly easy to learn when you are first getting started, but has many powerful features that allow advanced developers to create full Web sites, interactive games, or almost anything else they need.
Flash was originally developed under the name Future Splash. At the time, it was a simple tool for creating animation. Macromedia purchased it in 1997 and changed the name to Flash. Flash was the primary motivation for Adobe to purchase Macromedia in late 2006.
