Tim Cook has officially become the longest-serving CEO in Apple’s history, surpassing the legendary tenure of co-founder Steve Jobs. Since taking the helm on August 24, 2011, Cook’s leadership has spanned more than 5,091 days, marking a significant era of transformation and growth for the company.

Assuming the role after Jobs’ resignation, Cook faced enormous expectations and skepticism. However, he not only maintained Apple’s momentum but steered the company into new territory. Under Cook, Apple diversified its product line, launching iconic devices like the Apple Watch, AirPods, HomePod, AirTag, and, more recently, Apple Vision Pro. He also championed Apple’s transition to in-house Apple Silicon chips, further cementing the company’s reputation for ingenuity and performance.

Equally impressive is the expansion of Apple’s ecosystem and digital services under Cook’s guidance. Offerings such as Apple Pay, Apple Music, and Apple TV+ have become integral parts of the brand, fueling recurring revenue and deepening customer loyalty. During his tenure, Apple’s market value soared from $350 billion to over $3 trillion, making it the world’s most valuable publicly traded company. Notably, Apple became the first U.S. company to hit market capitalizations of $1 trillion in 2018, $2 trillion in 2020, and $3 trillion by 2023.

While some critics periodically question if Cook’s strategic vision can keep matching future demands, his track record speaks for itself. He has guided Apple through industry shifts, supply chain crises, and evolving consumer trends, maintaining the company’s dominance. With no retirement plans publicly announced, Cook’s legacy as Apple’s longest-serving chief executive continues to unfold, and the industry is closely watching what innovations will define his next chapter.
