An advertising network is an online network that connects advertisers to a small or large number of audience, allowing them to further their good or service. Advertising networks act as brokers that sustain themselves through the currency of the advertisers and their buyers. These networks, depending on size and exclusivity, will produce hundreds to millions of impressions per a certain period of time. This allows for the brands, or advertisers, to generate their advertisements in an efficient manner. A few examples of some notable advertising networks include, Bing Ads, Adform, Atlas Solutions, and Adcash. These networks generate a very high number of impressions for advertisers per month.
