On February 4, 2004, in an already crowded social media universe with sites like MySpace and Friendster, Harvard University student Mark Zuckerberg invented Facebook while in his college dormitory room.
The social media site was originally only made for Harvard University students to share information and be each other’s friends. Within 24 hours after it was first invented, 1,200 students had a Facebook profile, a number that has since grown to more than 1.3 billion all over the world.
In the years since its inception, Facebook has grown to include profiles of everyone from average citizens and celebrities to businesses and government agencies.
