An ad network is an aggregated ad inventory technology platform serving as a smart broker between publishers (supply sources) and advertisers (demand sources).
Ad networks were one of the first pieces of advertising technology that appeared in the mid ‘90s when online advertising first began, responsible for the very same things they are today—helping advertisers buy available ad inventory across publishers.
What Is Remnant Inventory?Remnant inventory is unsold ad inventory collected by Ad networks from all publishers and offer them as pool of impressions to advertisers at a much lower price than a publisher’s direct sales. This kind of inventory is often referred to as remnant inventory or non-premium inventory.
