Haider, M., & Kreps, G. (2004). Forty years of diffusion of innovations: Utility and value in public health. Journal of Health Communication, 9(Suppl1), 3-11.
This special issue of the Journal of Health Communication (Vol 9[1]) is created to mark the 40th anniversary of Diffusion of Innovations (DOI) model. Diffusion is the process through which an innovation, defined as an idea perceived as new, spreads via certain communication channels over time among the members of a particular social system. A great deal of research in a variety of academic disciplines (about 5,000 published studies so far) has been conducted on the diffusion of innovations, which can be applied to the recent spread of the Internet or to any other new idea. Everett Roger's ground-breaking model has contributed to a greater understanding ofof adoption of innovations, and it has held a broad scope of practical applications in the field of public health.
