Although its main principles were in use earlier, diffusion of innovations theory (diffusion theory) was first formally articulated by Everett M.rogers in the early I1960s. Areas of research where this theory has been applied include agriculture, health, teaching and learning, marketing and management, and, in the recent past, communication innovations involving new technologies, such as the Internet and e-mail. The four main elements of diffusion theory are embodied in a deceivingly simple definition: Diffusion is the process by which an innovation is communicated through channels over time among members of a social system (Rogers, 2003)
