Tim Cook is stepping down as CEO of Apple after 14 years and 7 months, a period marked by significant product innovations and strategic shifts. Cook succeeded Steve Jobs in 2011 and led Apple into new categories, starting with the Apple Watch in 2015, which became the world's most popular smartwatch and has been credited with saving lives through health monitoring features. Following this, the AirPods, launched in 2016, transformed the wireless earbuds market, becoming a favorite among consumers. Under Cook, Apple also transitioned from Intel processors to its own M series chips, significantly enhancing performance and efficiency in its Mac lineup. The introduction of the iPhone X in 2017 marked a pivotal shift towards an all-screen design, influencing both Apple's future devices and competitors. Additionally, Cook emphasized sustainability, aiming for Apple to become carbon neutral by 2030. As he departs, Cook leaves behind a legacy of innovation and a redefined Apple product ecosystem.
