[Philip Lelyveld comment: this is a familiar message from Prof. Christensen, but still a good one.]
Existing players in an industry almost always fail to appreciate how disruption will affect them or understand how to adapt to it, Harvard professor Clay Christensen says, and media companies are making all of those same mistakes.
Existing players are often good at what the Harvard scholar calls “sustaining” innovation, but they are rarely good at disruptive innovation. The latter is the kind that transforms something that used to be complicated and expensive — and therefore available only to the wealthy or those with special skills — and makes it available to a much broader group of users.
