Since Tim Cook became CEO in 2011, Apple has undergone significant changes. The company, already successful with the iPhone and iPad, expanded its ecosystem and introduced new product categories. Apple's net sales reached $416.2 billion in fiscal 2025, with over 2.5 billion active devices.
Under Cook's tenure, existing Apple products also evolved. The Mac transitioned to Apple's custom processors, and the iPhone gained new functionalities like a digital wallet and satellite communication. The services business grew to exceed $100 billion annually.
The Apple Watch, launched in 2015, initially served as an iPhone companion for notifications and activity tracking. Subsequent updates, particularly with Series 4 in 2018, added health features like ECG and fall detection. The watchOS 11 update in 2024 introduced sleep apnea notifications, the Vitals app, and Training Load, further expanding its health monitoring capabilities. The Apple Watch Series 11 in 2025 added sleep scoring and hypertension notifications, making it a comprehensive health device.
AirPods, initially wireless earbuds, became an integral part of the Apple ecosystem. Apple continued to add features and functionalities, solidifying their role beyond simple audio playback.
