  The diffusion of innovations theory has been studied for years. Previous
research efforts mainly focus on key elements, adopter categories, and the
process of innovation diffusion. However, most of them only consider single
innovations. With the development of modern technology, recurrent innovations
gradually come into vogue. In order to reveal the characteristics of recurrent
innovations, we present the first large-scale analysis of the adoption of
recurrent innovations in the context of mobile app updates. Our analysis
reveals the adoption behavior and new adopter categories of recurrent
innovations as well as the features that have impact on the process of
adoption.
