The term tech giant is used to describe any big technology establishment with a large global footprint. Typically, it is used to refer to the world’s biggest five tech companies—Amazon, Apple, Google (or Alphabet), Meta, and Microsoft—although other huge technology companies also qualify. These giants have a massive influence on the technology industry and the world as a whole.
Tech giants have a lot of power in their industries and are often accused of using that power to control the Internet, skew information or opinions, and create monopolies. Many are subject to anti-trust lawsuits, which seek to limit their control and increase competition for the benefit of consumers.
These giants make products or services that are widely used, which gives them outsized control over the Web and a valuable advertising space. They also innovate new technologies that can transform entire industries. Amazon’s e-commerce site is the world’s largest, giving them tremendous influence on what people buy and the data they generate; Apple makes iOS and macOS, the most widely used mobile and desktop operating systems; and Google owns the most popular search engine and various other useful products.
Some of the biggest tech giants have made a number of major acquisitions, such as Facebook purchasing WhatsApp and Instagram and Oculus VR, which created the first virtual reality headset. They also seek to dominate in certain areas of technology, such as with their cloud computing. Google, for example, acquired Mandiant to better protect its own cloud infrastructure.
