This paper focuses on the process of innovation diffusion through a population where sets of new members -- called generation cohorts -- enter the population over time. In certain cases where diffusion in a growing population does not follow the prototypical logistic pattern, disaggregating it by generation cohorts makes the diffusion process more apparent. Subsequent generation cohorts experience increased rates of diffusion and higher levels of early adoption. Moreover, the diffusion experienced by the existing population affects the diffusion path of later generation cohorts. After documenting the effect of generation cohorts on diffusion, strategic implications are considered, with incumbents and entrants competing to capture succeeding generation cohorts that each experiences its own path of diffusion.
