Clayton M Christensen, professor at Harvard Business School, shot to prominence with his book The Innovator's Dilemma: When New Technologies Cause Great Firms to Fail (1997). In this book he first came up with the concept of "disruptive innovation" which has proved very influential in understanding business and technological trends.
A disruptive innovation is an innovation that creates a new market and eventually disrupts an existing market displacing established firms in the process.
