The rhythm of mutation in the technical and scientific environment of the leading ‘post-industrial’ countries has led to the idea that the demand for communication has been provoked essentially by the massive arrival of new techniques of information and communication. An illusion and a tautology amply cultivated by inflation in promotional discourse about how to get out of the crisis, which has not hesitated to present the dissemination of new tools and networks as the most effective means to achieve the modernisation of the mode of growth and development. None the less, while these techniques clearly occupy a decisive place in the formulation of the demand for communication, it is equally obvious that they have nothing to do with its origins. To imagine otherwise is to become enclosed within sophistry, no more no less, and to ratify a new variant of technical determinism. The new demand for communication, and the new supply, have been generated in different places in consequence of multiple logics.
