In recent years, innovation diffusion models and their applications are increasingly studied because of the rapid development of technology. Since the publication of Norton and Bass (1987), the models on multi-generation diffusion have resulted in a body of articles, books, and reports. In this study, the progress of multi-generation innovation diffusion studies based on 44 research papers published from 1971 to 2018 is reviewed. Insights from different research streams are summarized and outlines an entry point for new researchers focusing on multi-generation innovation diffusion is provided.
