As of April 2012, Facebook has more than 900 million active users.
Zuckerberg was named four times in Time 100 respectively in 2009 as one of the 100 influential people of the world, in 2010 as Time magazine’s Person of the Year, in 2011 as one of the 100 influential people of the world and in 2012 in “The All-Time TIME 100 of All Time” by Joel Stein in Time. As of 2012, his personal wealth is estimated to be $17.5 billion, making him one of the world’s youngest billionaires.
He is one of the world’s richest men and according to him “I started Facebook in my messy Harvard dorm room in 2004, to help Harvard students and later other college students connect with one another online.”
The company is expected to start selling stock to the public for the first time and begin trading on the Nasdaq Stock Market on Friday. The IPO could value Facebook at nearly $100 billion, making it worth more than such iconic companies as Disney, Ford and Kraft Foods.
Zuckerberg was born in 1984 in White Plains, New York to Karen, a psychiatrist, and Edward Zuckerberg, a dentist. He and his three sisters, Randi, Donna, and Arielle, were brought up in Dobbs Ferry, New York. Zuckerberg was raised Jewish and had his bar mitzvah when he turned 13; he has since described himself as an atheist.
