This chapter provides an inventory and regrouping of the widely dispersed literature on technological incubators by considering the emergence of accelerators in the last decade, illustrated and supported by eight in-depth case studies of technology incubators and accelerators in Quebec (Canada). These cases enabled the development of an analytical framework adapted to the reality of the support organizations. The framework classifies incubators and accelerators into five profiles based on their overall strategies, goals and practices. This chapter provides an interesting overview of the impact of accelerators on the evolution of the incubation model through an analysis of the case studies. The proven efficacy of the former has contributed to the reinvention of the latter over a short time. Suggestions for future research in the field are outlined in the conclusion, based on a discussion of our findings and their limitations as presented in the chapter.
