Facebook, now officially operating under its parent company Meta Platforms Inc., is one of the world’s largest social networking platforms. It was launched on February 4, 2004, by Mark Zuckerberg along with his Harvard University roommates Eduardo Saverin, Andrew McCollum, Dustin Moskovitz, and Chris Hughes. Originally created for Harvard students, it quickly expanded to other universities and eventually became open to anyone aged 13 and older. The platform allows users to create profiles, connect with friends, share posts, photos, and videos, join groups, and follow pages. Its “News Feed” feature, introduced in 2006, became a central way for users to stay updated on friends’ activities. Facebook also revolutionized online interaction with features such as “Like” (2009), “Reactions,” and “Marketplace.” Over the years, Facebook has acquired major companies including Instagram (2012) and WhatsApp (2014), solidifying its dominance in social media. In 2021, the parent company was renamed Meta to reflect its focus on the metaverse—a digital world combining virtual and augmented reality. Despite facing criticism over privacy issues, misinformation, and data security, Facebook remains influential with over 3 billion monthly active users worldwide. It continues to shape how people communicate, share information, and build online communities.
