Following its acquisition of ScanScout in November, video ad network Tremor Media more than doubled the number of ads it served to U.S. users in December, according to data from comScore.
Meanwhile, rival networks ADAP.TV and BrightRoll also enjoyed substantial growth, growing the number of ads they served by more than 200,000 impressions each.
ComScore estimates Tremor served 1.02 billion ad impressions in December, representing 114 percent growth compared with the 477 million it served in November. The network also grew its reach from 22.4 percent of U.S. users to 28.6 percent during the same period.
As a result of that growth, the gap between Tremor and market leader Hulu has narrowed significantly in terms of the volume of ads served by each.
