Advertiser interest in purchasing real-time, impression-level inventory has led to explosive growth in ad spending on real-time bidding (RTB) inventory. Media-buying firm Accordant Media found worldwide real-time bidding inventory for banner and video ads across online and mobile placements grew 120% in Q1 2012. Though some countries saw growth rates for RTB ad inventory impressions grow more than 600%, the US still accounted for the greatest share (47%) of all RTB-based inventory.
