A common instructional task and a set of educational environments are hypothesized for analysis of media cost data. The analytic structure may be conceptulized as a three-dimensional matrix: the first vector separates costs into production, distribution, and reception; the second vector delineates capital (initial) and operating (annual) costs; the third vector presents cost as a function of environment. Per student equivalent annual costs are estimated for airborne television, Instructional Television Fixed Service (ITFS), satellite television, UHF television, closed circuit television, video tape recordings, film, radio, language laboratories, and dial access systems. The appendix analyzes componential and operating costs for five media systems (instructional television, audiovisual media system, educational radio, learning and language laboratories, dial access), using guidelines established in Volume I of the study. Estimated costs are presented graphically with price ranges and design considerations. Researchers must examine the possibilities of cost savings in media development and consider the relationship of instructional technology to the educational system, government, and the knowledge industry.
