The paper is concerned with reviewing basic quantitative models, and applying them to a case study in the field. In a review of the literature, quantitative models are classified into two classes. The first is concerned with the spread of a new product from its manufacture to the ultimate users or adopters, and focuses on the development of a product life cycle curve. In the second class, model parameters are given as functions are functions of some relevant controlled variables, and thus such models can be used for planning purposes.

The case study of a technological innovation indicates that during the early few years, sales are basically gained from consumers who purchase the product for the first time. In later years, sales are primarily acquired from repeat purchases by previous adopters. The paper illustrates the contribution of the research to the state of the art, and sheds light on directions for future research in order to make the models of diffusion of innovation theoretically more sound and practically.
