The deal could easily two fold the personal monetary status of the co-founder of Face Book Mark Zuckerberg.

The social and very popular networking site, called Facebook, has accumulated five hundred million dollars from a Russian investor and Goldman Sachs under a deal that valued the firm at fifty billion dollars as per statement made by people involved in the transaction. The deal transforms Facebook now valued more than companies like eBay, Time Warner and Yahoo.

The stake taken up by Goldman Sachs, reckoned as one of Wall Street's key investors, indicates the increasing strength of Facebook, which has already been giving competition to major firms like Google.

The new money will give Facebook more strength for stealing away valuable employees, develop new products and possibly follow purchasing deals. This will happen although it is not a publicly traded company. From the investment earlier shareholders might be allowed to get some cash from their shares in which employees of Facebook are included.

The new investment takes place at a time when the Securities and Exchange Commission has started an inquiry into the rising hot private market for shares in Internet companies, including Twitter, Facebook, the gaming site Zynga and LinkedIn, an online professional networking site.

According to some experts, the inquiry is focused to find out, if certain companies are improperly using the private market improperly for getting around public disclosure requirements.

The new money could also be a burden to Facebook to go public although its executives have resisted. With Microsoft and Google shares gaining popularity in the private market the firm was compelled to opt for the initial public offerings.

The social networking site of Facebook Inc.'s surpassed Google Inc.'s main site and Yahoo Inc.'s e-mail site as the most visited site on the Web in the U. S. in 2010.
