Summary: ``The adoption and diffusion of new ideas or new products by a social system has been studied extensively for the past twenty years. A great number of models have been developed to describe the time pattern of the spread of an innovation in such a system. We present in this paper a review of the most important models developed in a marketing purpose. More precisely, we consider the BASS model and some of its extensions. We will present in another paper [the authors, ``Les modèles de diffusion des produits nouveaux avec variables de marketing'', same journal, to appear] generalizations of these models which include marketing variables.''
