Technology executives dominated the top 10 of Forbes magazine's list of 400 richest Americans this year, with Microsoft co-founder and chairman Bill Gates retaining his place at the top of the annual list for the 14th time. According to Forbes, Gates is worth $59bn.
Five of the top 10 are technology executives. Larry Ellison from Oracle and Michael Dell from Dell were fourth and eighth respectively. Oracle's chairman is worth $26bn (£12.8bn), according to Forbes, while Dell's net worth is $17bn (£8.4bn).
Breaking into the top 10 for the first time were Google wunderkinds Sergey Brin and Larry Page, who also were among the youngest of the top 400 richest Americans. Both Google co-founders and co-presidents are 34 and shared the fifth spot with a net worth of $19bn (£9.4bn). Only the 317th richest American, John Arnold, a hedge fund billionaire in Houston, is younger than Brin and Page. Google's Page also caught up to Brin's bank account in 2007. Last year, Brin held the twelfth spot at $14bn (£7bn) in net worth, while Page was a hair behind at number 13 with $14bn (£7bn).
Number two on the list was Gates's friend Warren Buffett of Berkshire Hathaway, who has pledged a significant amount of his wealth to The Bill and Melinda Gates Foundation. Forbes said that Buffet is worth $52bn (£25.7bn).
While Sheldon Adelson, with a net worth of $28bn (£13.8bn), no doubt owes his number three spot to his Las Vegas casino and hotel holdings, he's a familiar name to tech veterans as the impresario once behind the now defunct Comdex mega tradeshow.
Microsoft co-founder Paul Allen slipped from his position at number five last year to number 11. Allen is worth $17bn (£8.4bn), according to Forbes. Current Microsoft chief executive Steve Ballmer, worth $15bn (£7.4bn), also fell from 15th last year to 16th this year.
Other high tech executives who made a strong showing on the list in 2007 are eBay 's founder and Chairman Pierre Omidyar, who came in 32nd, Amazon.com founder, chairman, chief executive and president Jeff Bezos, who is tied with SAS Institute's James Goodnight in 35th spot. Lastly Google's chief executive Eric Schmidt, came in 48th and is worth $6.5bn (£3.2bn).
