Update: From the LinkedIn blog:

LinkedIn Corporation announced today that it has filed a registration statement with the Securities and Exchange Commission for a proposed initial public offering of its Class A common stock. The number of shares to be offered and the price range for the offering have not yet been determined. A portion of the shares will be issued and sold by LinkedIn, and a portion will be sold by certain stockholders of LinkedIn.

Demand Media shares are listing today in the New York Stock Exchange under the DMD symbol, as the company’s IPO of 8.9 million shares priced out at $17 a share (above estimates of $114 – $16). 

The IPO raised a reported $151.3 million valuing the company at just under $1.5 billion. 

Demand Media’s much-anticipated initial public offering is coming next week, according to Kara Swisher, reporting for the Wall Street Journal’s All Things Digital. She says numerous sources "with knowledge of the situation" say it will happen after the company’s road show for investors. 

It’s possible that we’re at last digging out of the recession, given that the Dow’s flirting with 11,000 today.  It’s possible, too, that the people behind Hulu are ready to take advantage of this fact, as a new rumor indicates the company could go public early next year.

Skype announced today that it has filed a registration statement with the Securities and Exchange Commission for an initial public offering. From the release:

Facebook CEO Mark Zuckerberg spoke at the Reuters Global Technology Summit on Tuesday, and declined to confirm recent reports that the company had held discussions regarding $150 million in funding (as reported by VentureBeat) and turned down $200 million (as reported by TechCrunch).

Update: paidContent.org is reporting that eBay CEO John Donahoe says that the company is "still open to other offers" and that he will “maximize the value of Skype. Period." Any "reasonable offers" made between now and 2010 (when the proposed IPO is scheduled) will be evaluated.

At this point, we really haven’t seen a major Web 2.0 company make it through an IPO.

We’ve seen YouTube gobbled up by Google, and MySpace snagged by Rupert Murdoch’s News Corp. To date, they remain the companies that have truly defined success in the evolving Web 2.0 era.
