Apple introduced the Apple II personal computer in 1977, one year after the company was founded.
Steve Wozniak designed much of the Apple II, while Steve Jobs helped shape its presentation and commercial direction. Unlike many earlier hobbyist computers, it arrived as a relatively complete product with a keyboard and color graphics capability.
The Apple II became one of the earliest mass-produced personal computers. Its success helped provide Apple with the resources and reputation to develop later products such as the Macintosh, iPod, iPhone, and iPad.
The Apple II is sometimes confused with the Apple I, which was a smaller, earlier computer sold mainly as a kit. Apple’s modern market value comes from a broad ecosystem, but the Apple II remains a foundational product in the company’s history.
