“A disruptive technology or disruptive innovation is an innovation that helps create a new market and value network, and eventually goes on to disrupt an existing market and value network. The term is used in business and technology literature to describe innovations that improve a product or service in ways that the market does not expect. Although the term disruptive technology is widely used, disruptive innovation seems a more appropriate term in many contexts since few technologies are intrinsically disruptive; rather, it is the business model that the technology enables that creates the disruptive impact.”
