Twitter's MoPub mobile ad exchange has launched inventory packages to enable brands to segment and target ad inventory. Arranged by shared characteristics, the eight packages allow users to target inventory based on performance data or how recently it's been added to MoPub, said the company's director of product marketing, Emel Mutlu.
