Apple created the iPhone, first released in 2007, and remains among the world's highest-valued public companies.
Apple introduced the original iPhone on January 9, 2007, and released it in the United States on June 29 that year. The device combined a mobile phone, an iPod, and an internet communicator in one product, helping redefine the smartphone market.
Apple was founded in 1976 by Steve Jobs, Steve Wozniak, and Ronald Wayne. Its growth has come from hardware, software, services, and a tightly integrated ecosystem that includes the Mac, iPad, Apple Watch, AirPods, and App Store.
Market capitalization changes whenever Apple shares or its share count changes, so rankings can move relative to Microsoft, Alphabet, and other giants. Market cap is also different from annual revenue or total assets; it is the market value of a company's outstanding shares.
