Facebook, an American social media platform established in 2004 by Mark Zuckerberg, transformed from a college networking tool into a global service with over 3 billion monthly users. It allows users to share content, interact with others, and participate in communities, while undergoing scrutiny concerning privacy, false information, and societal influence. Authors such as David S.
Ferriero have pointed out its swift integration by governments and businesses, while Martin Weller observed its shift from a specialized tool to a mainstream communication platform. Zuckerberg’s 2018 Senate testimony underscored user control over personal data, yet disputes remain about its role in promoting divisive material. Facebook’s legacy embodies both its capacity to connect people and its struggles in maintaining a balance between freedom and accountability.
