Almost a third of the IT industry's 100 wealthiest players work in Internet-related ventures, according to Forbes magazine's annual listing. Many of them are way ahead of better-known executives like Eckhard Ffeiffer (chart position: 42), Lou Gerstner (50) and Craig Barrett (55). There's no great surprise who heads the list: Microsoft's Bill Gates, Paul Allen and Steve Ballmer, in the first, second and third slots, respectively. Forbes estimates Gates' wealth at $58.7 billion, though it's worth noting that this was calculated at the start of August before the summer's stock market plummets wiped an estimated $1.9 billion off Gates' worth. Still, what's a few billion among friends? In fact, many of the names listed made significant losses over the last month or so, largely because so much of their worth is solely based stock options at arguably inflated prices. Amazon.com CEO Jeff Bezos, for instance, saw his fortune grow to $2.1 billion -- making him number eight in the chart -- even though his company has yet to make a cent in profit and is unlikely to do so for some time. Yahoo co-founders David Filo and Jerry Yang, on the other hand, can at least say their company makes money, and it brought them $1 billion and $993.2 million, respectively, putting them at 15 and 16 in the chart.
