Look at the global cell-phone business. Just five years ago, three companies controlled 64% of the smartphone market: Nokia, Research in Motion, and Motorola. Today, two different companies are at the top of the industry: Samsung and Apple. This sudden complete swap in the pecking order of a global multibillion-dollar industry is unprecedented. Consider the meteoric rise of Groupon and Zynga, the disruption in advertising and publishing, the advent of mobile ultrasound and other "mHealth" breakthroughs (see "Open Your Mouth And Say 'Aah!'). Online-education efforts are eroding our assumptions about what schooling looks like. Cars are becoming rolling, talking, cloud-connected media hubs. In an age where Twitter and other social-media tools play key roles in recasting the political map in the Mideast; where impoverished residents of refugee camps would rather go without food than without their cell phones; where all types of media, from music to TV to movies, are being remade, redefined, defended, and attacked every day in novel ways--there is no question that we are in a new world.
