Federated Media blog ad network raises $4.5 million

[Updated: We’ve corrected the article below, based on further reporting. Regulatory filings about venture capital financings are tricky, because they’re often late, and misleading. That’s why the proposal to bring more transparency is a good one.]

Federated Media, a popular but sometimes controversial ad network for blogs, has raised another $4.5 million in funding, according to PE Hub’s read of the company’s recent regulatory filing.

Returning backers include New Enterprise Associates and Omidyar Network, according to the filing; FM has raised nearly $3 million to date, PE Hub reports. [Update: We’re told NEA didn’t invest, and its not clear why PE Hub reports this. The lead investor in FM has always been Panorama Capital, a group formerly part of JP Morgan Partners.].
