This document discusses disruptive innovation and provides examples to clarify the concept. It begins by defining innovation versus invention, and explaining that disruptive innovation occurs when a smaller company targets overlooked customer segments with a lower-cost product. The document then analyzes whether Uber qualifies as a disruptive innovation and concludes it does not, as it launched in major markets and did not initially appeal to non-consumers. Finally, the document provides examples of companies that were truly disruptive, such as Netflix targeting underserved customers through mail delivery before moving mainstream with streaming.
