Since its inception over two decades ago, the theory of disruptive innovation has sparked heated discussions. Especially because of the increasing importance of societal influences and novel forms of competition and technology, questions about its theoretical value and practical relevance remain. Researchers have focused on firm-internal factors of disruptive innovations to resolve discussions about the validity of the theory. However, the literature lacks an integrated understanding of contextual factors, such as demand, market structure, culture, and regulation, that influence disruptive innovation because of its dispersed, fragmented character across dis-ciplines. Our study addresses this fragmentation and lack of integrated understanding by systematically reviewing 62 articles. The study makes three main contributions. First, we integrate and synthesize the literature on contextual factors of disruptive innovations. Second, we derive a three-phase framework of contextual factors: (1) disruptive susceptibility, (2) emergence and diffusion, and (3) endgame and outcome. Third, we contribute to resolving discussions about the theory's core elements and its predictive value by showing how, depending on the societal, cultural, or market context, the implications of the theory can change. Overall, this article shows how disruptive innovation can start, and be started, by social change. We conclude by suggesting areas for future research.
