What is Big Tech?

Big Tech is the name given to the five largest companies in the information technology (IT) industry in the United States, and includes Meta (Facebook), Amazon, Apple, Google, and Microsoft. The members of Big Tech have become among the most valuable publicly traded companies in the world, with each having a market capitalization from USD 500 billion–2 trillion. Because Big Tech has so much power and international influence, concerns have repeatedly been raised that their monopolistic business practices are too centralized, focused on excessive profit, offer poor security and privacy, and feature widespread data theft.
