Abstract
Multimedia is defined as noun and adjective. The development and use of multimedia presentations are surveyed historically, and multimedia is considered a vehicle, technical but at the same time aesthetic, for communicating imaginative as well as factual material, and for entertaining as well as instructing. Aspects of theory, development, research, and practice are discussed, and sources of information about multimedia techniques are listed. Technical and engineering communicators are urged to experiment with multimedia as a dynamic means of imparting facts and establishing comprehension.
