October 14, 2005: Tim Cook takes the reins as Apple’s chief operating officer. His new role as Apple COO continues his climb through the company’s ranks and will lead to his appointment as CEO less than six years later.
“Tim has been doing this job for over two years now, and it’s high time we officially recognized it with this promotion,” Apple CEO Steve Jobs says in a statement. “Tim and I have worked together for over seven years now, and I am looking forward to working even more closely with him to help Apple reach some exciting goals during the coming years.”
Tim Cook becomes Apple COO
Apple benefited from one of the greatest leadership teams in business history. Steve Jobs dreamed up the products that made Apple a cultural phenomenon. Tim Cook made sure the company could deliver them to the world in mass quantities.
By the time Cook became Apple’s chief operating officer on this day in 2005, he was already reshaping the business with an almost obsessive focus on efficiency and execution. His promotion cemented his role as Jobs’ right-hand man and put him on the path to becoming CEO. It was a pivotal moment in Apple’s history, marking the rise of a different kind of leader — one who would prove that running the world’s most valuable tech company required more than visionary ideas.
Cook joined Apple in 1998 as senior vice president of operations after a short stint at Compaq Computer Corporation. He took over as Apple’s vice president of worldwide sales and operations in 2002.
Cook’s expertise centered on operations and logistics. He loved nothing more than whittling down on-hand inventory.
“You kind of want to manage it like you’re in the dairy business,” he once said. “If it gets past its freshness date, you have a problem.”
Within months of joining Apple, Cook slashed the company’s on-hand inventory from $400 million to just $78 million. He could be brutal with suppliers and people working under him. But he earned respect and became well-liked for his rational approach to problems.
With his October 14, 2005, promotion to COO, Cook became responsible for all of Apple’s worldwide sales and operations. He also led the company’s Macintosh division and worked with Jobs and other Cupertino execs “to lead Apple’s overall business.”
A different kind of Apple exec
At that point, Cook’s future leadership of Apple as CEO wasn’t guaranteed. However, his name obviously appeared on a very short list of people up for consideration. His promotion to COO certainly didn’t surprise anyone, though. He had worked closely with Jobs for years.
What was interesting about Cook was how much he differed from many others in Apple’s upper echelons. He was understated compared to Jobs and the likes of Scott Forstall, a senior vice president who dressed like the Apple co-founder. (Forstall even drove the same model silver Mercedes-Benz SL55 AMG as his boss.)
But Cook was like Jobs where it mattered. A hard-nosed negotiator, he proved tireless in his dedication to Apple — and obsessive about achieving feats most other companies viewed as impossible.
It certainly paid off. In recent years, Apple’s market capitalization soared beyond the $5 trillion mark, fueled by continued strong sales of iPhones, Macs and other devices, as well as steadily increasing revenue from services like iCloud+. (An emphasis on services stands as one of the hallmarks of Cook’s era as CEO.)
Tim Cook stepped down as Apple CEO on September 1, 2026, with former hardware chief John Ternus assuming the role. However, Cook remains a key factor in Cupertino’s continued success as he became the executive chairman of Apple’s board of directors.
