Sean Parker named president
The famous scene in The Social Network depicting Sean Parker discovering Thefacebook.com on a girl's laptop has some truth to it. According to a Vanity Fair profile, Parker came across the site on the laptop of his roommate’s girlfriend, who was a Stanford student at the time.
Parker was named Facebook’s president in the summer of 2004, and although his tenure ended after an arrest for cocaine possession in 2005, his impact on the company is considered pivotal to its success. The aforementioned 2010 Vanity Fair profile says, "Had he not joined founder Mark Zuckerberg in Palo Alto in the summer of 2004, when the fledgling Facebook was just five months old, the service almost certainly would not be the colossus it is today."
