Facebook is a classic Silicon Valley success story: from a Harvard dorm to the top of the world.
It has made Mark Zuckerberg into a legendary figure and turned a hoodie and tennis shoes into the height of tech industry fashion.
These days, Facebook is worth $364 billion, with over 1.71 billion people using the site every month.
Here's the story behind Facebook's insane growth, from February 2004 through today.

Facebook got its start at Harvard's Kirkland House dormitory — the same dorm that Wallace Shawn (who played Vizzini in "The Princess Bride" and the voice of "Toy Story's" Rex) lived in during his Harvard years.
In 2003, Harvard sophomore Mark Zuckerberg would build a program called "Face mash." It was a Hot or Not-style app using the pictures of his classmates that he hacked from the school administration's dormitory ID files. It got 22,000 page views from 450 people in the first four hours it was up. A few days later, Harvard ordered it to be taken down, citing copyright and security concerns.
Zuckerberg faced disciplinary action from Harvard but was allowed to stay at the school. Undeterred, he launched "TheFacebook" on February 4, 2004.
