Google's parent company Alphabet Inc. has been described as a Big Tech company.

The company went public via an initial public offering (IPO) in 2004. In 2015, Google was reorganized as a wholly owned subsidiary of Alphabet Inc.

Apple Inc. is an American multinational technology company headquartered in Cupertino, California, in Silicon Valley, best known for its consumer electronics, software and online services. Founded in 1976 as Apple Computer Company by Steve Jobs, Steve Wozniak and Ronald Wayne, the company was incorporated by Jobs and Wozniak as Apple Computer, Inc. the following year. It was renamed to its current name in 2007 as the company had expanded its focus from computers to consumer electronics. Apple has been described as a Big Tech company.

The company was founded to market Wozniak's Apple I personal computer. Its successor, the Apple II, became one of the first successful mass-produced microcomputers. Apple introduced the Lisa in 1983 and the Macintosh in 1984 as some of the first computers to use a graphical user interface and a mouse. By 1985, internal conflicts led to Jobs leaving the company to form NeXT and Wozniak withdrawing to other ventures; John Sculley served as CEO for over a decade. In the 1990s, Apple lost considerable market share in the personal computer industry to the lower-priced Wintel duopoly of Intel-powered PC clones running Microsoft Windows, and neared bankruptcy by 1997. To overhaul its market strategy, it acquired NeXT, bringing Jobs back to the company. Under his leadership, Apple returned to profitability by introducing the iMac, iPod, iPhone, and iPad devices; creating the iTunes Store; launching the "Think different" advertising campaign; and opening the Apple Store retail chain. Jobs resigned in 2011 for health reasons, and died two months later; he was succeeded as CEO by Tim Cook.

Microsoft Corporation is an American multinational technology conglomerate headquartered in Redmond, Washington. Founded in 1975, the company became influential in the rise of personal computers through software like Windows, and has since expanded to Internet services, cloud computing, artificial intelligence, video gaming, and other fields. Often described as a Big Tech company, Microsoft is the largest software company by revenue, one of the most valuable public companies, and one of the most valuable brands globally.

Microsoft was founded by Bill Gates and Paul Allen to market BASIC interpreters for the Altair 8800. It rose to dominate the personal computer operating system market with MS-DOS in the mid-1980s, followed by Windows. During the 41 years from 1980 to 2021 Microsoft released 9 versions of MS-DOS with a median frequency of 2 years, and 13 versions of Windows with a median frequency of 3 years. The company's 1986 initial public offering (IPO) and subsequent rise in its share price created three billionaires and an estimated 12,000 millionaires among Microsoft employees. Since the 1990s, it has increasingly diversified from the operating system market. Steve Ballmer replaced Gates as CEO in 2000. He oversaw the then-largest of Microsoft's corporate acquisitions in Skype Technologies in 2011, an increased focus on hardware that led to its first in-house PC line, the Surface, in 2012, and the formation of Microsoft Mobile through Nokia. Since Satya Nadella took over as CEO in 2014, the company has changed focus towards cloud computing, as well as its acquisition of LinkedIn for $26.2 billion in 2016. Under Nadella's direction, the company has expanded its video gaming business to support the Xbox brand, establishing the Microsoft Gaming division in 2022 and the acquisition of Activision Blizzard for $68.7 billion in 2023.
