The Social Network - 2010

In 2003, Harvard University student Mark Zuckerberg is dumped by his girlfriend Erica Albright. He returns to his dorm drunk and writes a scathing blog entry about her. This inspires him to create an on-campus website called Facemash which allows users to rate the attractiveness of female students using photographs pilfered from various university systems. Mark receives six months of academic probation after traffic to the site crashes parts of Harvard's network. Facemash's popularity and the fact that Mark created it in one night while drunk brings him to the attention of Cameron and Tyler Winklevoss and their business partner Divya Narendra. The Winklevoss twins invite Mark to their final club, where Mark accepts a job as programmer for a proposed dating website they call Harvard Connection which will be exclusive to Harvard alums.

Mark approaches his friend Eduardo Saverin and tells him of his idea for what he calls "Thefacebook", an online social networking website exclusive to Harvard University students. He explains that this would mimic the popularity of FaceMash but since signing up would be consensual it would avoid the ethical problems of the earlier site. Eduardo agrees to help Mark, providing $1,000 to help start the site. They distribute the link to Eduardo's connections at the Phoenix S-K final club, and it becomes popular throughout the student body. When they learn of Thefacebook, the Winklevoss twins and Narendra believe Zuckerberg has stolen their idea while stalling on their website. Tyler and Divya want to sue Mark for intellectual property theft, but Cameron convinces them to settle the matter as "gentlemen of Harvard".

During a visiting lecture by Bill Gates, fellow Harvard University student Christy Lee introduces herself and her friend Alice to Eduardo and Mark and asks the boys to "Facebook me". Christy's use of this phrase impresses both of them. Christy invites them to a bar, where Mark runs into Erica, who is not aware of Thefacebook because she is not a Harvard student. Mark decides to expand the site to Yale University, Columbia University and Stanford University as Thefacebook grows in popularity, while the Winklevoss twins and Narendra watch "their idea" advance without them. Cameron refuses to sue them, instead accusing Mark of violating the Harvard student Code of Conduct. Through their father's connections they meet with Harvard President Larry Summers, who is dismissive towards the twins and sees no potential value in either a disciplinary action or in Thefacebook website itself....
