The history of Facebook can’t be told without a mention of Facemash.com, the controversial website Zuckerberg created in October 2003. After hacking the online repositories containing headshots of Harvard undergrads who lived on campus, Zuckerberg uploaded the stolen images to Facemash, where users chose which of two randomly generated students paired with each other was more attractive.
Zuckerberg also infamously blogged while building the site, admitting to being "a little intoxicated" at the time. Harvard shut the site down a few days later and charged Zuckerberg with breaching security, violating copyright and violating privacy, with the potential for expulsion from the school. The charges were later dropped.
