This Day in History:, Facebook Launches.
February 4, 2004.
Initially called "The Facebook," 
the site was launched 
on this day by Harvard 
sophomore Mark Zuckerberg.
"The Facebook" served as a social network for 
Harvard students to connect with their classmates.
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.
The platform continues to 
stir controversy over privacy 
and data sharing concerns
