Steve Jobs and Steve Wozniak founded Apple Computers, Inc. on April 1, 1976. The two started their business by assembling Apple I computers in Jobs' garage and selling them without keyboards, monitors or even a casing.
In 1978, Apple had sales of $7.8 million, and in 1980, when Apple went public, it grossed $117 million. Apple revolutionized personal computing by introducing color graphics for the first time, and Jobs continued developing revolutionary ideas. He left Apple for a period of time, founding NeXT Software and purchasing Pixar, then came back to Apple to develop the iPod and iPhone. Jobs died in 2011. Wozniak, who left Apple in 1987, went on to become a philanthropist and speaker.
