Tim Cook's 15-year Apple reign ends with record profits.

Tim Cook's 15-year Apple reign ends with record profits. The supply-chain engineer transformed Apple from a $350 billion company at Jobs' death to a $4 trillion valuation today. While lacking Jobs' revolutionary product reveals, Cook built a services empire generating nearly a quarter of revenue by 2024. The Apple Watch became the world's top smartwatch, Airpods redefined wireless audio, and custom chip development reduced supplier dependence. Cook's strategic pivot to digital content, apps, and cloud services proved highly profitable but drew monopoly scrutiny globally. His China strategy maximized efficiency until trade tensions forced diversification to India, Vietnam, and domestic production. John Ternus takes over in September, inheriting a vastly more profitable but less innovative company than the one Cook inherited from Jobs.
