The Big Four is a name used to describe the four multinational technology companies Google, Amazon, Facebook, and Apple. The term was coined by Eric Schmidt, Phil Simon, and Scott Galloway as driving a large amount of growth in technology. The Big Four are sometimes referred to as GAFA, an acronym for Google, Amazon, Facebook, and Apple. The term Big Five is sometimes used to include Microsoft, another major technology company.
The term refers to companies driving large societal change, rather than just the largest tech companies. Schmidt, Simon, and Galloway consider some large companies such as IBM and Microsoft to be driving less change than the Big Four.
