Steve Wozniak, Steve Jobs, and Ronald Wayne established Apple Computer Company on April 1, 1976, to develop and market Wozniak's Apple I personal computer. Jobs and Wozniak established Apple Computer, Inc. in 1977. The Apple II, the company's second computer, became a best-seller and one of the first mass-produced microcomputers. Apple went public in 1980 and quickly became a commercial success. The business created computers with innovative graphical user interfaces, including the original Macintosh, which debuted in 1984 in a highly acclaimed advertisement. By 1985, the high expense of its products, as well as power struggles among executives, were causing problems. Wozniak left Apple amicably and moved on to other endeavors, while Jobs bitterly left Apple and started NeXT, taking some personnel from Apple with him.

During the 1990s, Apple's market share declined as Microsoft Windows on Intel-powered PC clones became more popular due to their lower price. In 1997, Apple bought NeXT to improve its operating system strategy and bring Steve Jobs back to the company. Jobs successfully led Apple to profitability over the next decade by introducing innovative products such as the iMac, iPod, iPhone, and iPad, along with memorable advertising campaigns, the Apple Store retail chain, and acquiring new companies to expand its product portfolio.

In August 2018, Apple became the first publicly traded U.S. company valued at over $1 trillion, reaching $2 trillion in August 2020, and $3 trillion in January 2022. As of January 2023, its value is around $2.2 trillion. Despite criticism regarding its labor practices, environmental practices, and business ethics, Apple has a strong following and high brand loyalty, and is ranked among the world's most valuable brands.
