The theory was popularized by Everett Rogers in his book Diffusion of Innovations, first published in 1962. [1] Rogers argues that diffusion is the process by which an innovation is communicated through certain channels over time among the participants in a social system. The origins of the diffusion of innovations theory are varied and span ...
The diffusion of innovations according to Rogers. With successive groups of consumers adopting the new technology (shown in blue), its market share (yellow) will eventually reach the saturation level. When the first edition of Diffusion of Innovations was published in 1962, Rogers was an assistant professor of rural sociology at Ohio State ...
In the 1962 book, Diffusion of Innovations, Everett Rogers defines sociological diffusion of innovation as a process in a social system where an innovative idea or concept is spread by members of the social group through certain channels. He identifies four elements that influence how and how quickly a new idea spreads: [3] The innovation itself
The rate of diffusion is the speed with which the new idea spreads from one consumer to the next. Adoption is the reciprocal process as viewed from a consumer perspective rather than distributor; it is similar to diffusion except that it deals with the psychological processes an individual goes through, rather than an aggregate market process.
The Bass model or Bass diffusion model was developed by Frank Bass. It consists of a simple differential equation that describes the process of how new products get adopted in a population. The model presents a rationale of how current adopters and potential adopters of a new product interact.
In diffusion of innovation theory, a pro-innovation bias is a belief that innovation should be adopted by the whole society without the need for its alteration. [1] [2] The innovation's "champion" has a such strong bias in favor of the innovation, that they may not see its limitations or weaknesses and continue to promote it nonetheless. [3]
An example put forth by Rogers in Diffusion of Innovations was that of the fax machine, which had been around for almost 150 years before it became popular and widely used. It had existed in various forms and for various uses, but with more advancements in the technology of faxes, including the use of existing phone lines to transmit ...
Rogers' bell curve. Similarly, in the later stages, the opposite mistakes can be made relating to the possibilities of technology maturity and market saturation. The technology adoption life cycle typically occurs in an S curve, as modelled in diffusion of innovations theory. This is because customers respond to new products in different ways.
