For connecting more than half a billion people and mapping the social relations among them, for creating a new system of exchanging information and for changing how we live our lives, Mark Elliot Zuckerberg is TIME's 2010 Person of the Year.
At 26, Zuckerberg is the youngest "Person of the Year" since the first one chosen, Charles Lindbergh; he was 25 when he was named in 1927, Time said Wednesday. Zuckerberg beat out Britain's Queen Elizabeth II by just two weeks: She was 26 when she was named in 1952.
Zuckerberg has built Facebook into an international phenomenon by stretching the lines of social convention and embracing a new and far more permeable definition of community. In this new world, users are able to construct a social network well beyond what would ever be possible face-to-face.
"I'm trying to make the world a more open place," Zuckerberg says in the "bio" line of his own Facebook page.
