Top billionaires: who is the richest person in the world?
Facebook helps WhatsApp founders onto Forbes's rich list, while Bill Gates regains his spot at the top
TECHNOLOGY entrepreneurs feature heavily in the Forbes list of global billionaires this year, with Bill Gates regaining his place as the richest person in the world.
The Microsoft founder missed out on the top spot for the last four years, but he is back after a bounce in the company's shares, with a net worth of $76bn.
Facebook founder Mark Zuckerberg, 29, was crowned the "biggest gainer" as shares in the social network boomed and his net worth jumped from $15.2bn to $28.5bn over the past year.
Facebook helped propel numerous other fortunes too. The company's chief operating officer Sheryl Sandberg and long-time vice president Jeff Rothschild joined the ranks of the world's billionaires for the first time this year, while WhatsApp founders Jan Koum and Brian Acton also joined the list thanks to a $19bn deal with Facebook last month.
With a net worth of $32bn, Amazon's Jeff Bezos came out marginally higher on the list than Zuckerberg, as did Google's Sergey Brin, whose net worth was $31.8bn.
Of the 1,645 members of the Forbes Billionaires list, 31 were under the age of 40, and 172 were women, with a record 42 female newcomers.
