Apple was founded in 1976 by Steve Jobs, Steve Wozniak and Ronald Wayne. They introduced the Apple I computer kit and later the Apple II, which was one of the first successful mass-produced microcomputers. Throughout the 1980s and 1990s, Apple released many influential products but also struggled at times. Steve Jobs was later rehired as CEO and introduced groundbreaking products like the iMac, iPod, iPhone and iPad that cemented Apple's position as a leader in personal technology and drove tremendous growth. Jobs passed away in 2011 and Tim Cook assumed the role of CEO, continuing to lead the company into the present day.
