Diffusion of innovations
- Is a theory that seeks to explain how, why, and at what rate new ideas and technology spread through cultures.
- Everet Rogers, a professor of communication studies, popularized the theory in his book Diffusion of Innovations
- The book says that diffusion is the process by which an innovation is communicated through certain channels over time among the participants in a social system.
- The book explains the theory that four main elements influence the spread of a new idea: the
- innovation itself, communication channels, time, and a social system.
Diffusion of innovation Process
- Diffusion occurs through a five–step decision-making process.
- Ryan and Gross first identified adoption as a process in 1943. Rogers’ five stages (steps): awareness, interest, evaluation, trial, and adoption are integral to this theory.
- In later editions of Diffusion of Innovation, Rogers changes his terminology of the five stages to: knowledge, persuasion, decision, implementation, and confirmation.
