What the CIA failed to do in 60 years, Zuck has done in seven: knowing what 800 million people more than 10 per cent of the world's population think, read and listen to, plus who they know, what they like and where they live, travel, vote, shop and worship. Zuckerberg, a Harvard dropout, is now creating his own monetary system, Facebook Credits, to facilitate transactions and profits. With a net worth of $17.5 billion, he is now America's 14th-richest man.

2011 highlight: The movie inspired by his life, "The Social Network," which depicts Zuckerberg as a cold-hearted dweeb, won three Oscars.
