Apple Inc. Chief Executive Officer Steve Jobs, who transformed the company he started at age 21 from a personal-computer also-ran into the world’s largest technology company, resigned.
Jobs, who will become chairman, was on medical leave since Jan. 17 after combating a rare form of cancer since 2003 and surviving a liver transplant in 2009. He is succeeded by Chief Operating Officer Tim Cook, 50, who has been running day-to-day operations.
