The first time that Apple, Google and Microsoft found themselves sharing the same digital space was 1998. They were radically different companies and they would subsequently fight a series of pitched battles for control of different parts of the digital landscape. They could not know of the battles to come. But they would be world-changing. IN Digital Wars, Charles Arthur assesses who are the victors in each of the battles over search technology, mobile music, smartphones and the tablet market, and which company can reap the rewards of wealth, control over another part of the digital landscape and the chance to determine the shape of the future.
