The history of multimedia and descriptions of various multimedia events from 1900 to 1972 are presented. The development of multimedia events is described for four eras and four main classifications of events: multiscreen presentations, electronic media and performers, environmental theater, and environments. Five appendixes include a discussion of terms used in the report, a chart of multimedia events, a chronological list of important technical advances in multimedia equipment, letters, and an informal index. A 20 page bibliography concludes the document. (CH)
