The latest comScore numbers are out and TubeMogul ranked in the top ten in terms of video ads served, coming in right behind CBS Interactive and Microsoft. According to comScore, TubeMogul served over 345 million video ads and reached nearly two in ten video viewers in the U.S. Given that TubeMogul’s real-time media buying platform for brand advertising only launched in April, this is a rapid rise and a sign of confidence from the major trading desks signed globally, who made this possible.
