Bill Gates retakes the title of the world's richest man
Gates had been the richest person in the world before, of course. But the computer billionaire lost that title in 2007. Now, however, Gates' personal fortune has grown to $72.7 billion, a 16 percent rise from the previous year (according to the Bloomberg Billionaires Index).
How did Gates get on top of the financial world again? The main reason seems to be an increase in Microsoft's worth. Slim also saw a decrease in his net worth, losing about $3 billion after Mexico's government passed legislation that hurt the business mogul's dominance in the Central American mobile-phone industry.
The fact that Bill Gates has managed to become the world's richest man is especially impressive when you consider the amount of money he has given away -- $28 billion of Gates' money has been used to fund the Bill & Melinda Gates Foundation.
Wondering who else is super-rich this year? Warren Buffett comes in at number 3 on the richest-people list, with a personal net worth of $59.7 billion. In fourth place is Spain's Amancio Ortega, with $56 billion. Rounding out the top five richest men is IKEA founder Ingvar Kamprad, who has $55.6 billion.
