In 1976, when Jobs was just 21, he and Wozniak started Apple Computer in the Jobs’ family garage. They funded their entrepreneurial venture by Jobs selling his Volkswagen bus and Wozniak selling his beloved scientific calculator. Jobs and Wozniak are credited with revolutionizing the computer industry with Apple by democratizing the technology and making machines smaller, cheaper, intuitive and accessible to everyday consumers.
Wozniak conceived of a series of user-friendly personal computers, and — with Jobs in charge of marketing — Apple initially marketed the computers for $666.66 each. The Apple I earned the corporation around $774,000. Three years after the release of Apple's second model, the Apple II, the company's sales increased by 700 percent to $139 million.
In 1980, Apple Computer became a publicly-traded company, with a market value of $1.2 billion by the end of its very first day of trading. Jobs looked to marketing expert John Sculley of Pepsi-Cola to take over the role of CEO for Apple.
The next several products from Apple suffered significant design flaws, however, resulting in recalls and consumer disappointment. IBM suddenly surpassed Apple in sales, and Apple had to compete with an IBM/PC-dominated business world.
