An analysis of strategies used to disseminate the PLATO system

Two aspects of efforts to disseminate an innovative computer-assisted instructional system called PLATO between 1972 and 1976 are addressed. The first pertains to the dissemination problems encountered and resolved by the system developers. The second covers dissemination modus operandi chosen by the developers to bring PLATO to the attention of large numbers of people. An ex post facto analysis of data obtained suggested PLATO developers made dissemination decisions that reflected viable dissemination theory and practice of the time, committed substantial resources to the dissemination process, and selected what appeared to be a cost-effective marketing strategy. Perhaps the most important consequence of these actions is that PLATO flourished throughout the 1970s and continues to flourish.
