Facebook is the world's largest social networking platform, founded in 2004 by Mark Zuckerberg alongside co-founders Eduardo Saverin, Andrew McCollum, Dustin Moskovitz, and Chris Hughes while they were students at Harvard University. Originally limited to Harvard students before expanding to other universities and eventually the general public, Facebook has grown to serve approximately 3 billion monthly active users worldwide, making it the most widely used social media platform in history. In 2021, the parent company rebranded to Meta Platforms, reflecting its strategic pivot toward building the metaverse, while the Facebook app and brand retained their original name. Headquartered in Menlo Park, California, at the Meta campus, Facebook offers a comprehensive social networking experience including personal profiles, News Feed, Groups, Marketplace, Events, Stories, Reels short-form video, Facebook Watch, Facebook Gaming, and Facebook Dating. The platform serves as a critical tool for businesses through Facebook Pages, Facebook Ads, and the Meta Business Suite, enabling targeted advertising that reaches billions of users based on detailed demographic and behavioral data. Facebook Messenger, originally integrated into the main platform, operates as a standalone messaging app with over a billion users. The platform has profoundly influenced global communication, politics, media consumption, and digital advertising, generating the vast majority of Meta's advertising revenue alongside Instagram.
