Steve Jobs was 21 years old when he co-founded Apple Computer Company in 1976.
Jobs, along with his friend Steve Wozniak, started Apple in a garage in Los Altos, California. Their first product was the Apple I, a single-board computer that was sold primarily to hobbyists.
The company's success came with the release of the Apple II in 1977, which was a more user-friendly and commercially successful computer.
Jobs's vision and Wozniak's technical expertise led to the creation of one of the most iconic and influential technology companies in history.
