Internet audience measurement firm comScore has filed with the Securities and Exchange Commission to raise up to $86.25 million in an initial public offering.

In 2006, comScore generated revenue of $66.3 million, primarily from subscription fees. The company plans to list its stock on Nasdaq under the symbol "SCOR," but revealed no other details about the number of shares or expected price range.

The company collects data from more than 2 million Internet users and uses it to project online behavior for the total population.

Credit Suisse Securities will serve as sole book-running manager for the offering; Deutsche Bank Securities Inc., William Blair & Company, L.L.C., Friedman, Billings, Ramsey & Co., Inc., and Jefferies & Company Inc. will serve as co-managers.
