Tim Cook became CEO of Apple in August 2011, succeeding Apple founder Steve Jobs, who passed away in October 2011. Cook had previously served as Apple’s chief operating officer, overseeing the company’s sales and operations across the globe. He first joined Apple in 1998 after a 12-year career at IBM and gigs at Compaq and Intelligent Electronics. As CEO of Apple, Cook has been criticized for overstretching the company, introducing flawed or lackluster products, and losing market share to competitors like Amazon and Google. Under his leadership, Apple posted its first revenue decline in 13 years due to slowing iPhone sales, sparking alarm among investors. But Cook is leading the company’s push into new areas, such as health care, media, and self-driving cars, while continuously working to improve much-loved products like the iPhone, with the goal of ensuring longevity for Apple. Originally from Alabama, Cook came out as gay in October 2014, making him the first openly gay CEO of a Fortune 500 company.
