Facebook is a social media platform that was founded by Mark Zuckerberg and his college roommates Eduardo Saverin, Andrew McCollum, Dustin Moskovitz, and Chris Hughes in 2004. It quickly gained popularity and has since become one of the largest and most influential social networking sites in the world.
Facebook allows users to create a personal profile, connect with friends and family, and share updates, photos, and videos. Users can also join groups and pages based on their interests, participate in discussions, and follow the updates of public figures, brands, and organizations.
Over the years, Facebook has expanded its features and services. It acquired several other companies, including Instagram and WhatsApp, which now operate as separate platforms under the Facebook umbrella. Facebook Messenger is the messaging app associated with the platform.
