Diffusion of Innovations Model

Research output: Chapter in Book/Report/Conference proceeding › Entry for encyclopedia/dictionary

Abstract

The diffusion of innovations model explains why some, but not other, innovations are taken up widely and rapidly in a social system. By some counts, the diffusion of innovations model is the most cited communication theory. This entry summarizes the diffusion of innovations model, including its historical development, core concepts, and theoretical propositions. The entry reviews key concepts such as innovations' attributes, adopter categories, opinion leadership, communication channels, and reinvention, and illustrates them with examples from health communication research. The entry concludes with major criticisms of the theory and its research paradigm.
