Business Insider recently released its list of the most powerful people in the world, and 12 of our top 50 were innovators, CEOs, and influencers from the tech world. To determine the ranking, we considered more than 100 of the most influential players in business, politics, and entertainment, and evaluated their influence using metrics in four major areas: economic power, command, newsworthiness, and impact — a subjective measure that captures how important they are in their respective spheres.
