Ad Network

An Ad Network is a company that acts as an intermediary between advertisers looking to run campaigns and publishers (websites, apps) with available Ad Inventory. The network aggregates ad space from numerous publishers and offers it to advertisers, simplifying the buying process. Ad networks often provide targeting capabilities, Ad Serving technology, and reporting. Examples include Google Display Network and Facebook Audience Network. While vital, some of their role is evolving with the rise of Ad Exchanges and Programmatic Advertising.
