Anyone who worked in newspaper publishing over the past twenty years will at some point have found themselves metaphorically beaten about the head with the 1997 book The Innovator’s Dilemma: When New Technologies Cause Great Firms To Fail, by Harvard Business Professor Clayton Christensen. The book’s premise, wrapped up in plenty of talk about value creation and S curves, is that companies with big businesses cannot change the basic, successful core functions of those businesses quickly enough to innovate against their coming obsolescence. Newspapers, too, were becoming obsolete, but the grand publishing houses that produced them would not be able to meet the speed required by new technologies (the internet and social media) to adapt. - www.cjr.org
