Why do we spend so much time counting other people's money? Because these moguls have the power to shape our world.
This 25th year of tracking global wealth was one to remember. The 2011 Billionaires List breaks two records: total number of listees (1,210) and combined wealth ($4.5 trillion). This horde surpasses the gross domestic product of Germany, one of only six nations to have fewer billionaires this year.
More than 50 reporters in 13 countries worked on compiling the list this year, valuing individuals' public holdings, private companies, real estate, yachts, art and cash. Net worths were locked in using stock prices and exchange rates from Feb. 14.
So who are the world's top 10 billionaires? Read on to find out.
