Christianization of the Roman Empire as diffusion of innovation looks at religious change in the Roman Empire's first three centuries through the lens of diffusion of innovations, a sociological theory popularized by Everett Rogers in 1962. Diffusion of innovation is a process of communication that takes place over time, among those within a social system, that explains how, why, and when new ideas (and technology) spread. In this theory, an innovation's success or failure is dependent upon the characteristics of the innovation itself, the adopters, what communication channels are used, time, and the social system in which it all happens.
