Mr Christensen used the term to describe innovations that create new markets by discovering new categories of customers. They do this partly by harnessing new technologies but also by developing new business models and exploiting old technologies in new ways. He contrasted disruptive innovation with sustaining innovation, which simply improves existing products. Personal computers, for example, were disruptive innovations because they created a new mass market for computers; previously, expensive mainframe computers had been sold only to big companies and research universities.&quot;
