Rubicon Project: Online CPMs Up 34 Percent In Q4

Los Angeles-based Rubicon Project, the online ad optimization firm, said today that its analysis finds that online spending in Q4 of 2009 was up, resulting in an increase in CPMs by 34%. The firm--which has been running its own series of reports on the online advertising market--attributed the increase in CPMs to holiday ad spending, as well as interesting in celebrity news topics. Rubicon said it expects 2010 to be a "strong year" for digital advertising. The firm is venture backed by $42M in funding from Clearstone Venture Partners, Mayfield Fund, IDG Ventures and GE/NBC Universal's Peacock Equity Fund.
