From Wikipedia, for that don’t know the term: “a concept in economics that describes a process in which new innovations replace and make obsolete older innovations.”
Ironically, I had to google it, and agree with the comment.
You should read The Innovator's Dilemma as well, as it goes into detail on this concept, basically explaining why and how technological disruption occurs from the point of view of the disruptor and disruptee.
