Tứ đại quyền lực, a concept popularized by Scott Galloway, refers to the four most influential forces in today’s world: Amazon, Apple, Google, and Facebook. These tech giants shape not only the economy but also our daily lives, influencing everything from shopping habits to social interactions.

Galloway argues that their dominance stems from creating unique ecosystems that foster user loyalty. Amazon revolutionized retail; Apple redefined technology branding; Google transformed information access; and Facebook shifted social networking dynamics.

Understanding these forces is crucial for businesses and consumers alike. They not only dictate market trends but also highlight the importance of digital strategy in an increasingly connected world.
