Business Insider: Under CEO Tim Cook's watch, Apple has sold hundreds of millions of iPhones, booked hundreds of billions of dollars in profit, and launched new products like AirPods and Apple Watch. In fact, Cook says, he's never had a bad year as CEO of Apple. "I've only had good years. No, seriously," he said in an interview with Fast Company. "Even when we were idling from a revenue point of view -- it was like $6 billion every year -- those were some incredibly good years because you could begin to feel the pipeline getting better, and you could see it internally. Externally, people couldn't see that," he continued.
