The Mobile advertising industry landscape consists of two major parts – Supply, that is presented by publishers and a SSP (stands for Supply Side Platform) that aggregates mobile inventory across hundreds of thousands of publishers and Demand, that is presented by a DSP (stands for Demand Side Platform) that allows advertisers to place mobile ads in publishers inventory. A Mobile Ad Network function is to serve a middle point between these two ends of the value chain, moving inventory across both supply and demand, either directly or via reselling or re-broking of inventory.
