Facebook Turns 5
(CNN) -- A Web site started by a student as a way of staying in touch with friends celebrated its fifth birthday Wednesday as a billion-dollar business and a global phenomenon.
Mark Zuckerberg was 19 when he launched Facebook from a Harvard dorm in 2004. Within 24 hours, more than 1,000 of his Harvard classmates had signed up for the social-networking site and one month later half of those on campus had a profile.
Five years on, the Web site claims more than 150 million users worldwide while Zuckerberg, now 24, was named the youngest billionaire on the planet -- with an estimated fortune of $1.5 billion -- last year by Forbes magazine.
