Yesterday, industry experts said the public offering will not only make billionaires of Google's founders but will also help rejuvenate the technology sector's search engine and online advertising markets. With 200 million queries a day, Google is the world's largest search engine.

A Google public offering, which is being led by Morgan Stanley and Credit Suisse First Boston, has been rumored for more than a year. Google founders have relished the relative freedom of operating as a private company. They acknowledged their hesitancy to take the company public, restating that view in a letter enclosed in the SEC filing.

In the first disclosure of the powerhouse's finances, the SEC filing shows that Google's net revenue last year was $961.9 million, a 177 percent jump from its 2002 net revenue. In the three months that ended March 31 this year, Google's net revenue was $389.6 million, up from $178.9 million in the same quarter a year earlier.
