This Memorandum defines and describes communication media; discusses the difference between information and instruction, instructional media, and instruction aids; and proposes a set of criteria by means of which communication media may be distinguished from nonmedia, one medium distinguished from another, and discrete media distinguished from multimedia applications. A two-dimensional classification system is proposed: In one dimension, seven classes are defined, based on ways of representing information; in the other, communication media are divided into two groups, telemedia and recording media. This study, the first in a more extensive treatment of the subject, was conceived to fill a need for information on communication theory that is useful to those who must make decisions concerning the applications of this new technology. It is limited to describing the characteristics of each medium that determine its best uses. All major available and soon-to-be-available media are included in the discussion (28 in all). 131 pp. Refs. (MW)

Our mission to help improve policy and decisionmaking through research and analysis is enabled through our core values of quality and objectivity and our unwavering commitment to the highest level of integrity and ethical behavior. To help ensure our research and analysis are rigorous, objective, and nonpartisan, we subject our research publications to a robust and exacting quality-assurance process; avoid both the appearance and reality of financial and other conflicts of interest through staff training, project screening, and a policy of mandatory disclosure; and pursue transparency in our research engagements through our commitment to the open publication of our research findings and recommendations, disclosure of the source of funding of published research, and policies to ensure intellectual independence.
