The FT reports today that Google is about to go to an initial public offering, or IPO, which its sources value at between $15 billion and $25 billion. CNET puts the figure more conservatively at $2 billion. But the search engine giant's 29-year-old co-founder says his company has no immediate plans.

The flotation of Google has been eagerly anticipated for three years. Many expect it to revitalise tech and internet stocks across the board and compare it to the successful flotation of Netscape in 1995.

That flotation of the company behind Navigator, the first mainstream web browser, is seen as the point when investors took internet companies seriously and the conception of the dot.com bubble.

According to the Financial Times, the Silicon Valley-based company is thinking of holding a massive on-line auction for its shares in March 2004, in part to break Wall Street's hold on the IPO business.

The FT cites an unnamed source "close to the company," and estimates Google's current profits at around $150 million on revenues of $500 million.

However, CNET News.com quotes co-founder Sergey Brin saying the company does not need the case and that, while it would be "nice to have the currency" of a public company, there is no date set.

"There are significant management distractions to be a public company," Brin said at a Search Engine Strategies conference. But he did add, "there's a good chance we're eventually going to do it."

It was the year of Netscape's $1 billion flotation that Brin, then 23, met fellow Stanford University graduate Larry Page, then 24 and at the time, best known for having built a working printer out of Lego.

In January 1996 Brin and Page began work on a search engine called BackRub, named for its ability to analyse the "back links" pointing to a given web site.

BackRub evolved into Google in 1998, named after the word "googol," a mathematical term for a 1 followed by 100 zeros – a higher number than even the most optimistic valuations of Brin and Page's company.
