The Diffusion of Innovation
The diffusion of innovation is a theory that seeks to explain how, why, and at what rate new ideas and technology spread through cultures. The origins of the diffusion of innovation theory are varied and span multiple disciplines. Everett Rogers, a professor of rural sociology, popularized the theory in his 1962 book Diffusion of Innovations. He said diffusion is the process by which an innovation is communicated through certain channels over time among the members of a social system. Rogers synthesized research from over 508 diffusion studies and produced a theory for the adoption of innovations among individuals and organizations. Rogers (1962) espoused the theory that there are four main elements that influence the spread of a new idea:
- The innovation - According to Rogers, an innovation is "an idea, practice, or object that is perceived as new by an individual or other unit of adoption. "
- Communication channels - These are "the means by which messages get from one individual to another. "
- Time - Rogers wrote that "the innovation-decision period is the length of time required to pass through the innovation-decision process. The rate of adoption is the relative speed with which an innovation is adopted by members of a social system. "
- Social system - According to Rogers, a social system is "a set of interrelated units that are engaged in joint problem solving to accomplish a common goal. "
Diffusion of innovations manifest themselves in different ways in various cultures and fields and is highly subjective to the type of adopters and innovation decision process. Marketers are particularly interested in the diffusion process as it determines the success and failure of any new product introduced in the market. They usually look forward to procuring the largest amount of adoption within the shortest period of time. Thus, it is quite important for a marketer to understand the diffusion process so as to ensure proper management of the spread of the new product or service.
Technology and Market Share
