Premji ahead of Google's duo

Azim Premji, chairman of domestic IT major Wipro, has made it to Forbes' list of the world's 10 richest tech titans.

Premji, with a net worth of $13.3 billion, has been placed at the sixth position, ahead of Google founders Sergey Brin and Larry Page, eBay founder Pierre Omidyar, and founder of German business software major SAP Hasso Plattner.

Microsoft founder Bill Gates, who has remained the world's richest man for 12 consecutive years, tops the list, with a net worth of $50 billion.

Others on the list include Microsoft co-founder Paul Allen at the second position with a net worth of $22 billion; Dell founder Michael Dell at the third position with a net worth of $17.1 billion; Oracle co-founder Larry Ellison, who is fourth with $16 billion; and Microsoft CEO Steve Ballmer at the fifth position with a net worth of $13.6 billion.

Incidentally, Premji is among the select few on the list who remain actively involved in the day-to-day operations of their companies.

Three of the 10 "" Plattner, Paul Allen, and Pierre Omidyar "" are not actively involved in the companies they founded, while Gates has announced his plans to move away from the corporate world, the business magazine said.

Even those tech titans who remain involved in their companies, often pursued second lives outside the office, the magazine noted. For instance, Larry Ellison does not even maintain an office at Oracle's Silicon Valley headquarters.

The world's ten richest tech billionaires collectively have a net worth of $174.2 billion, which is more than the gross domestic product of Israel. Azim Premji, a Stanford graduate, is India's second-richest man after steel magnate LN Mittal.
