Infographic: Next Generation 911 Technology Adoption Lifecycle
In 1962, Everett M. Rogers, an assistant professor of rural sociology at Ohio State University, published a theory he described as the "diffusion of innovations" in a book of the same name. Rogers, who later in his career became a distinguished professor emeritus in the communications and journalism department at the University of New Mexico, developed the theory to describe how innovation adoption plays out in any given social group. Rogers broke the theory down to five distinct categories: innovators, early adopters, early majority, late majority, and laggards.
