MICROSOFT CO-FOUNDER Bill Gates has once again taken up the mantle as the world's richest person.
Gates had held the position of world's richest person for over a decade until Mexican telecoms giant Carlos Slim overtook him in 2007. With Slim's telecoms business faltering, Gates became the world's richest person again, with Bloomberg estimating his net worth at $72.7bn.
Gates' net worth has shot up an impressive 16 percent in 2013, while Slim's holdings in his America Movil company have fallen by 14 percent, wiping $3bn off his worth. Despite Gates being synonymous with Microsoft, most of his wealth is now in other investments, with the software developer making up only 25 percent of his total investments.
Despite Gates no longer relying on Microsoft stock for most of his wealth, the software developer's shares have done surprisingly well this year, rising by over 25 percent in 2013 on the back of impressive financial results. Gates has also donated a significant chunk of his wealth to the Bill and Melinda Gates Foundation, which Bloomberg estimates is worth $28bn.
Google's co-founders Sergey Brin and Larry Page have also enjoyed Google's recent stock price surge, which has seen its shares trade up to over $900, a 40 percent jump in the last six months. Bloomberg rates Page as slightly richer than Brin, with the pair's net worths pegged at $26.3bn and $25.9bn, respectively, though what's $400m between friends? µ
