Facebook is a social media platform that was launched in 2004. It allows users to create a personal profile, connect with friends and family, and share updates, photos, and videos. Facebook has become one of the largest and most popular social networking platforms in the world, with over 2.8 billion monthly active users as of 2021.

In addition to connecting people, Facebook also provides businesses with advertising and marketing opportunities, as well as features such as Marketplace for buying and selling items, Groups for connecting with like-minded individuals, and Facebook Watch for watching videos. However, there has been some criticism over the years for its handling of user data and privacy.
