Flash is a multimedia authoring program developed by Adobe that enables designers to tell interactive, multimedia stories on the Web. Flash presentations can bring together text, photos, data files, video, audio and animated graphics to deliver information in a non-linear format, allowing the user to sample various aspects of the story at will. Flash can be used to create complex and visually rich games, slide shows, interactive infographics and much more. Flash presentations offered by news sites often are produced as interactive complements to the traditional investigative and explanatory projects they produce for print.
