This Day in History:, Facebook Launches.

It was based on Zuckerberg's other social media site, FaceMash, in which male students voted on the attractiveness of female students.
By the end of the first day, more than 1500 Harvard students signed up for "The Facebook.".
Today, Facebook has more than 2.8 billion users worldwide.
