It was a classic modern business story: two Canadian entrepreneurs, Mike Lazaridis, a bookish innovator, and Jim Balsillie, and agressive entrepreneur, build an iconic brand that would forever change the way we communicate. From its humble beginnings in an office above a bagel store in Waterloo, Ontario, BlackBerry outsmarted the global giants with an addictive smartphone that generated billions of dollars. Its devices were so ubiquitous that even President Barack Obama favoured them above all others. But just as it was emerging as the dominant global player, BlackBerry took a dramatic turn. The story of one of the most spectacular technological upsets of the 21st century. Unlike Enron, which was undone by its executives' illegal activities, or Lehman Brothers, which collapsed as part of a larger global banking crisis, BlackBerry's rise and fall is a modern-day tale of the unrelenting speed of success and failure. The account of how two mismatched CEOs outsmarted more-powerful competitors with a combination of innovation and sharp-elbowed tactics; and how, once on top of the world, they lost their way. The company responded too slowly to competitors' innovations, and when it finally made its move, it stumbled with delayed, poorly designed and unpopular smartphones. A little more than a decade after Research In Motion introduced the BlackBerry, it is now struggling to survive. Its share of the US phone market fell from 50 per cent in 2009 to about one percent in 2013, showing just how aggressive, fast and unforgiving today's global business market can be. In 2013 the shareholders of BlackBerry approved a motion to change the legal name of the company from Research In Motion Limited to BlackBerry Limited.
