Steve Jobs returned to Apple in 1997, leading a turnaround by simplifying its product line and focusing on groundbreaking innovations like the iMac and iPhone. His approach emphasized design and user experience, which helped redefine technology consumption. In contrast, Tim Cook took over in 2011 and expanded Apple's reach, transforming it into a global powerhouse. Under Cook's leadership, Apple diversified its product offerings and prioritized operational efficiency, turning services like iCloud and the App Store into significant revenue streams. While Jobs was known for his category-defining innovations, Cook has focused on refining existing products and enhancing the overall ecosystem, making Apple one of the world's most valuable companies.
