The wildly enthralling and entertaining story of Apple's monopolistic impulses and the global business and political forces arrayed against its $3 trillion empire. iWar is a saga of corporate intrigue, control, and competition, featuring some of the world's most brilliant and powerful minds. It is the story of Apple, the tech corporation which has built near unassailable market power through its iPhone and app ecosystem and controls not only commerce, but also culture, and -- increasingly -- the flow of ideas. And it is the story of a powerful cadre of tech moguls determined to take it down. Over time, a loose and disparate group of billionaires, each driven by their own reasons, has formed to challenge Apple's supremacy, including Daniel Ek (Spotify), Tim Sweeney (Epic Games/Fortnite), Mark Zuckerberg (Facebook/Meta) and Elon Musk (Twitter/X). With in-depth reporting, Wall Street Journal business columnist Tim Higgins chronicles these tech moguls and their quest to weaken a powerful rival, aiming at destroying the Walled Garden around Apple's iPhone Empire, while telling a larger story of the global digital and information economy.
