Adobe Flash (previously called Shockwave Flash and Macromedia Flash) is a set of multimedia technologies developed and distributed by Adobe Systems and earlier by Macromedia. Since its introduction in 1996, Flash technology has become a popular method for adding animation and interactivity to web pages; Flash is commonly used to create animation, advertisements, various web page components, to integrate video into web pages, and more recently, to develop rich Internet applications.
Flash can manipulate vector and raster graphics and supports bi-directional streaming of audio and video. It contains a scripting language called ActionScript. It is available in most common web browsers and some mobile phones and other electronic devices (using Flash Lite). Several software products, systems, and devices are able to create or display Flash, including the Adobe Flash Player. The Adobe Flash Professional multimedia authoring program is used to create content for the Adobe Engagement Platform, such as web applications, games and movies, and content for mobile phones and other embedded devices.
Files in the SWF format, traditionally called "ShockWave Flash" movies, "Flash movies" or "Flash games", usually have a .swf file extension and may be an object of a web page, strictly "played" in a standalone Flash Player, or incorporated into a Projector, a self-executing Flash movie (with the .exe extension in Microsoft Windows). Flash Video (FLV) files have a .flv file extension and are used from within .swf files. * Macromedia Flash 2 (1997) Features: Support of stereo sound, enhanced bitmap integration, buttons, the Library, and the capability to tween color changes.
* Macromedia Flash 3 (1998) Features: Brought improvements to animation, playback, and publishing, as well as the introduction of simple script commands for interactivity. As of 1998, Macromedia has shipped 100,000 Flash products.
* Macromedia Flash 4 (1999) Features: Achieved 100 million installations of the Flash Player, thanks in part to its inclusion with Microsoft Internet Explorer 5. Flash 4 saw the introduction of streaming MP3s and the Motion Tween. Initially, the Flash Player plug-in was not bundled with popular web browsers and users had to visit Macromedia website to download it; As of 2000, however, the Flash Player was already being distributed with all AOL, Netscape and Internet Explorer browsers. Two years later it shipped with all releases of Windows XP. The install-base of the Flash Player reached 92 percent of all Internet users.
* Macromedia Flash 5 (2001) Features: Flash 5 was a major leap forward in capability, with the evolution of Flash's scripting capabilities as released as ActionScript. Flash 5 also saw the ability to customize the authoring environment's interface.
* Macromedia Generator was the first initiative from Macromedia to separate design from content in Flash files. Generator 2.0 was released in April 2001 and featured real-time server-side generation of Flash content in its Enterprise Edition. Generator was discontinued in 2002 in favor of new technologies such as Flash Remoting, which allows for seamless transmission of data between the server and the client, and ColdFusion Server.
* In October 2000, usability guru Jakob Nielsen wrote a polemic article regarding usability of Flash content entitled "Flash 99% Bad". (Macromedia later hired Nielsen to help them improve Flash usability.)
* In September 2001, a survey made for Macromedia by Media Metrix showed that out of the 10 biggest websites in the United States, seven were making use of Flash content.[citation needed]
* Macromedia Flash MX was released on March 15, 2002, with the new Macromedia Flash Player 6 with support for video, application components, shared libraries, and accessibility.
* Macromedia Flash Communication Server MX, also released in 2002, allowed video to be strea
