With the Internet taking a dominant role in corporate training, education, retail, and customer based product exploration, authors of Web-based information need to ensure that the media they deliver is accessible to the widest possible audience. Whether users have a visual, auditory, physical, or developmental disability, accessible multimedia can enhance and promote the message delivery through the chosen medium. This paper outlines some of the multimedia technologies currently available on the Web and the means to make them more accessible. It discusses Web audio and video captioning in Realmedia, Windows media, and QuickTime; Macromedia Flash, one of the fastest growing Web media formats; PowerPoint for the Web and four techniques that can be used to render PowerPoint information accessible to those with disabilities; Scalable Vector Graphics (SVG), an XML based language that allows images, text and vector graphics to be programmed directly into the Web interface; and Portable Document Format (PDF), which has become a standard protocol for the distribution of electronic documents via the Web.
