In their book with the programmatic title Communication of Innovations, Rogers and Shoe- maker (1972, p. 20) propose a diffusion process parallel to the SMCRE model (Source– Message–Channel–Receiver–Effect): the inventor replaces the “source,” the innovation the “message,” diffusion channels the “channels,” the adopter the “receiver,” and adoption the “effects.” While this formula fully satisfied the need for a loose structure capable of integrating a large variety of results, this approach also cemented a strongly linear understanding of communication and, hence, of the communication of innovations.
