Verizon has tapped AOL’s Platform-A (NYSE: AOL) digital ad agency network to sell its online and mobile advertising inventory with an extensive agreement including ad serving, targeting, and inventory management capabilities for display, mobile and video advertising services. In essence, Platform-A becomes the exclusive manager of Verizon’s inventory and and have exclusive guaranteed placement rights within the Verizon network; all other sales partners are selling on a blind-network basis. The deal also extends Verizon’s existing partnership with Third Screen Media, Platform-A’s mobile ad serving platform. The announcement emphasizes the kind of cohesion AOL wants to achieve with its ad offerings, especially since Advertising.com President Lynda Clarizio replaced Curt Viebranz as president last month because the integration was going too slowly.
