Behind the bitter rivalry between Apple and Google - and how an epic battle is reshaping the way we think about technology. The rise of iPhones, smartphones and tablets has changed the world. At the centre of this are Apple and Google, two companies who have steamrolled the competition. In the age of the Android and the iPad, these corporations are locked in a battle that will play out beyond the marketplace, in the courts and on screens around the world. Fred Vogelstein has reported on this rivalry for more than decade and has rare access to the boardrooms where company dogma translates into ruthless business; to outsize personalities like Steve Jobs and Eric Schmidt; and inside the deals, transactions, lawsuits and allegations. Apple and Google are brazenly poaching each other's employees. They bid up the price of each other's acquisitions for spite, and they forge alliances with major players like Facebook and Microsoft in pursuit of market dominance. 'Dogfight' is not just a story about what devices are going to replace our TVs, phones, laptops, and music players. It's about who will control what we see on those devices and where that content will come from. This is the future of media, entertainment, communication and information around the globe.
