The iPhone, Apple's single largest-selling product and the device that completely redefined the mobile industry, has helped catapult CEO Tim Cook to the top of Fierce Wireless' 25 Most Powerful People in Wireless survey. Cook was ranked just above Google's Larry Page and the CEOs of all four major US wireless carriers, among others in the industry. Together, Apple and Samsung garner more than 100 percent of the cell phone industry's profits, and the iPhone remains the single most popular brand in the industry.
