On May 18, Facebook CEO Mark Zuckerberg rang the Nasdaq opening bell and the social network became a public company, trading under the ticker symbol "FB."
There was plenty of drama surrounding Facebook's initial public offering, but the most unique story was of graffiti artist David Choe. Choe was hired by then Facebook president Sean Parker to paint a mural at Facebook's first office in Palo Alto in 2005. When the mural was finished, Parker gave Choe the option of taking cash or stock options. He took the stock and went from being homeless to being a millionaire.
