<P> In the 1993 first edition of Multimedia: Making It Work, Tay Vaughan declared "Multimedia is any combination of text, graphic art, sound, animation, and video that is delivered by computer . When you allow the user--the viewer of the project--to control what and when these elements are delivered, it is interactive multimedia . When you provide a structure of linked elements through which the user can navigate, interactive multimedia becomes hypermedia ." </P> <P> The German language society Gesellschaft für deutsche Sprache recognized the word's significance and ubiquitousness in the 1990s by awarding it the title of German' Word of the Year' in 1995 . The institute summed up its rationale by stating "(Multimedia) has become a central word in the wonderful new media world". </P> <P> In common usage, multimedia refers to an electronically delivered combination of media including video, still images, audio, and text in such a way that can be accessed interactively . Much of the content on the web today falls within this definition as understood by millions . Some computers which were marketed in the 1990s were called "multimedia" computers because they incorporated a CD - ROM drive, which allowed for the delivery of several hundred megabytes of video, picture, and audio data . That era saw also a boost in the production of educational multimedia CD - ROMs . </P> <P> The term "video", if not used exclusively to describe motion photography, is ambiguous in multimedia terminology . Video is often used to describe the file format, delivery format, or presentation format instead of "footage" which is used to distinguish motion photography from "animation" of rendered motion imagery . Multiple forms of information content are often not considered modern forms of presentation such as audio or video . Likewise, single forms of information content with single methods of information processing (e.g. non-interactive audio) are often called multimedia, perhaps to distinguish static media from active media . In the fine arts, for example, Leda Luss Luyken's ModulArt brings two key elements of musical composition and film into the world of painting: variation of a theme and movement of and within a picture, making ModulArt an interactive multimedia form of art . Performing arts may also be considered multimedia considering that performers and props are multiple forms of both content and media . </P>
