Key quotes:
The term was defined and first analyzed by the American scholar Clayton M. Christensen and his collaborators beginning in 1995, and has been called the most influential business idea of the early 21st century.
Disruptive innovations tend to be produced by outsiders and entrepreneurs, rather than existing market-leading companies.
In his sequel with Michael E. Raynor, The Innovator's Solution, Christensen replaced the term disruptive technology with disruptive innovation because he recognized that few technologies are intrinsically disruptive or sustaining in character; rather, it is the business model that the technology enables that creates the disruptive impact. However, Christensen's evolution from a technological focus to a business-modelling focus is central to understanding the evolution of business at the market or industry level.
