Tech billionaires in the top 100 added $52.9 billion (£33 billion) to their fortunes this year, more than any other industry
Bloomberg Markets annual ranking of the world's top 100 richest people reveals the collective fortune of the top 100 billionaires rose by an eye-watering $43 billion in 2014. That means this years bilionaires are worth a grand total of $2.2 trillion.
Here are the ten richest tech-heads.
1. 10. Azim Premji, Wipro, $16.2bn (£10.1bn)
Indian chairman of Wipro, Azim Premji, 69, has been steering the company since the late 1960s. Back then Wipro was a hydrogenated cooking fat company. Now it is a $7 billion IT, research and development and BPO firm with a presence in 60 countries.
Premji graduated from Stanford University with a degree in electrical engineering.
American-born Paul Allen, 61, raked in an extra $1.7 billion (£1.1 billion) last year, boosting his fortune to the equivalent of an estimated £11 billion. Allen is known for co-founding Microsoft with Bill Gates in 1975.
3. 8. Steve Ballmer, Microsoft, $21.2bn (£13.4bn)
In August Steve Ballmer, 58, gave up his seat on Microsoft's board of directors citing a busy schedule and confidence in the company's current and future financial performance. He had retired as CEO of Microsoft six months prior, but still boosted his wealth during 2014, to the tune of $3.4 billion (£2.2 billion).
4. 7. Jack Ma, Alibaba, $25.9bn (£16.4bn)
The 50-year-old chairman and founder of Alibaba, a chinese e-commerce giant, made $22.3 (£14.1) billion this year. The group is planning to grow its business internationally, perhaps beyond e-commerce, in the pursuit of new consumer data.
On their first day of trading in September, shares of Alibaba stock opened at $92.70 on the New York Stock Exchange.
5. 6. Jeff Bezos, Amazon, $29.6bn (£19bn)
Amazon founder and CEO Jeff Bezos has long argued that investing for growth is the right strategy for Amazon. The company made a big acquisition this year, picking up the gaming site Twitch for almost $1 billion (£6 million).
Bezos announced a surprise plan to buy The Washington Post for an alleged US$250 million in cash last year.
6. 5. Sergey Brin, Google, $32.1bn (£20.3bn)
Google's other co-founder, Sergey Brin, 41, now heads up special projects. He amassed $99 million (£63 million) last year alone, bumping him up the list.
7. 4. Larry Page, Google, $32.3bn (£20.4bn)
Google's CEO is not fond of a 40-hour work week, he revealed during the summer. But he has hit headlines most recently for a corporate shakeup at the internet giant. Several Google executives took a step back as Page put Sundar Pichai in charge of several major divisions.
8. 3. Mark Zuckerberg, Facebook, $34.9bn (£22bn)
In the year he turned thirty, Zuckerberg added $10.2 billion (£6.4 billion) to his fortune, making him the youngest billionaire in the world.
9. 2. Larry Ellison, Oracle, $42.6bn (£27bn)
Larry Ellison, 70, stepped down as Oracle's CEO in September, but maintained a role as CTO. His wealth dropped by 1.1 billion in 2014, but not by enough to knock him off the second spot in the Bloomberg's tech wealth list. Amongst the world's billionaires, across all industries, Larry is eighth richest.
10. 1. Bill Gates, Microsoft, $85.3bn (£54bn)
The wealthiest billionaire in the world, not just in tech, Microsoft's Bill Gates, 58, comes out top again. He brought in $6.7 billion (£4 billion) in 2014, bringing his fortune to over $85 billion dollars (£54 billion).
