Apple CEO Tim Cook Steps Down After 15-Year Tenure; John Ternus Takes Over
Tim Cook officially stepped down as Apple CEO on September 1, 2026, after leading the company for fifteen years. John Ternus, Apple's senior vice president of hardware engineering, officially became the new chief executive officer. Cook will remain at Apple as executive chairman, continuing to assist with policy and government relations. During Cook's tenure, Apple grew from a $350 billion company to a $4.6 trillion giant, becoming one of the most valuable companies in history. Cook oversaw the launch of major product lines including the Apple Watch, AirPods, and Apple TV+, while annual revenue quadrupled to over $416 billion. However, Cook's leadership has drawn criticism for Apple's sluggish response to artificial intelligence, with the company falling behind competitors like Microsoft and Google. Ternus faces the challenge of accelerating Apple's AI strategy and competing in what many analysts see as a critical moment for the entire tech industry. The transition comes just one week before Apple's fall product launch, where Ternus will debut new devices including Apple's first foldable iPhone.

How different outlets framed it
Left-leaning coverage: Progressive outlets highlight concerns about Apple's delayed and dependent AI strategy under Cook, suggesting the company relied too heavily on existing product success rather than investing boldly in next-generation technologies. Some coverage notes Cook's struggles with what critics describe as an insular corporate culture that hindered innovation and fast decision-making in the critical AI era.
Right-leaning coverage: Conservative outlets focus on Cook's cultivation of government relationships, particularly with the Trump administration, which Ternus will need to maintain. Some right-leaning sources applaud the leadership transition as bringing a product-focused engineer to the role, and note positively that Cook remains as executive chairman to maintain policy relationships with Washington.
