Apple cofounder Steve Jobs speaking with hands slightly raised
Apple cofounder Steve Jobs
  • When Steve Jobs returned to Apple, the company was in dire straits. 
  • He became CEO again and turned Apple around via new products and a Microsoft investment.
  • During Jobs' tenure, Apple launched the iMac, iBook, iPod, Mac OS X, iPhone, iPad, and more.

Much of Apple's success is due to the vision of Steve Jobs, the late cofounder. Without him, Apple as we know it today might not even exist.

In 1976, after he dropped out of college, Jobs cofounded Apple with his high-school friend, Steve Wozniak, while they were still in their 20s, according to "Steve Jobs," a biography by Walter Isaacson.

Jobs would leave Apple in 1985 to start a new company, NeXT.
