History of Innovation
market needs vs.
A new product or service that enters at the low end of the market and gradually moves up-market, displacing existing, established products. The change driving this disruption may, in itself, be a minor or incremental technological innovation.
New technology applied to solve an existing need in a new way. The HP Inkjet printer is the classic example here, having displaced earlier impact printhead technologies with a new and better way to put ink on paper.
