Everett M. "Ev" Rogers (March 6, 1931 – October 21, 2004) was an American communication theorist and sociologist, who originated the diffusion of innovations theory and introduced the term early adopter.
Some of the Bass-Model extensions present mathematical models for the last two (Maturity and Decline). MS-Excel or other tools can be used to solve the Bass model equations, and other diffusion models equations, numerically. Mathematical programming models such as the S-D model apply the diffusion of innovations theory to real data problems. [81]
The sociological theory of diffusion is the study of the diffusion of innovations throughout social groups and organizations. The topic has seen rapid growth since the 1990s, reflecting curiosity about the process of social change and "fueled by interest in institutional arguments and in network and dynamic analysis."
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 ...
Everett Rogers' "Diffusion of Innovations" cites one study in which two-thirds of respondents accredited their awareness to the mass media rather than face-to-face communication. Similarly, critics argue that most of Lazarsfeld's findings pertain to learning factors involved with general media habits rather than the learning of particular ...
The concept of development communication policy science has reference to the following: a) Diffusion model which enunciates that 'that the role of communication was (1) to transfer technological innovations from development agencies to their clients, and (2) to create an appetite for change through raising a 'climate for modernization' among ...
Communication theories vary substantially in their epistemology, and articulating this philosophical commitment is part of the theorizing process. [1] Although the various epistemic positions used in communication theories can vary, one categorization scheme distinguishes among interpretive empirical, metric empirical or post-positivist, rhetorical, and critical epistemologies.

This theory is one of several models that try to explain the diffusion of innovations, ideas, or commercial products. Opinion leaders play an important role in information flow, because we tend to seek advice from others in the social environment.
