Apple introduced the Macintosh computer in 1984 and is often ranked among the world's highest-market-cap companies.
The Macintosh launched on January 24, 1984, after a famous Super Bowl advertisement directed by Ridley Scott. Its graphical user interface and mouse distinguished it from many contemporaneous personal computers, although Apple was not the first company to use those ideas commercially.
Apple was incorporated in 1977 by Steve Jobs, Steve Wozniak, and Ronald Wayne. The company later expanded from computers into the iPod, iPhone, iPad, Apple Watch, services, and custom-designed chips. The iPhone, released in 2007, became the central product in Apple's modern business.
Market capitalization changes daily with share price, so rankings among the largest companies can change. Apple is frequently compared with Microsoft, Saudi Aramco, Alphabet, Amazon, and other major public companies; revenue, profit, and market value are different measurements.
