Concepto de innovación y difusión

"The diffusion of an innovation has traditionally been defined as the process by which that innovation "is communicated through certain channels over time among the members of a social system" (Rogers, 1983: 5). As such, there are four key elements in the diffusion process: theinnovation, channels of communication, time, and the social system. An innovation is any idea, object, or practice that is perceived as new by members of the social system and can range from a rumor to a rocket ship, a surfboard to a supermarket scanning system. Communication channels are the means by which information is transmitted to or within the social system. Mass media communication channels include radio, television, newspapers, and magazines. Interpersonal communication channels are the face-to-face linkages between two or more members of the social system." (PP 15).


"Time relates to the rate at which the innovation is diffused or the relative speed with which it is adopted by members of the social system. In the present context, the social system consists of individuals, organizations, or agencies that share a common "culture" and are potential adopters of the innovation. Hence, members of a social system can range from students enrolled in a specific course or consumers living in a particular neighborhood, to business organizations and governmental agencies, to states and nations." (PP 16)
