Top Ad Networks and Mobile Ad Networks: A Reference Directory
Ad networks were among the first pieces of advertising technology introduced in the mid-1990s. They helped publishers sell available ad space to multiple advertisers, allowing buyers to purchase inventory from many different sites through a single platform rather than negotiating with each publisher individually.
What Is an Ad Network and How Does It Work?
An ad network is a technology platform that acts as a broker between a group of publishers and a group of advertisers.
Ad networks collect unsold ad inventory from multiple publishers and offer that pooled inventory to advertisers at prices considerably lower than a publisher's direct sales rate. This type of inventory is commonly referred to as non-premium or remnant inventory.
Today, however, many networks also give advertisers access to premium inventory alongside remnant supply.
While ad networks were originally designed for display advertising — banner ads on websites — modern networks operate across many formats and channels, including video, native, in-app mobile, and OTT.
Here's a simple representation of how ad networks work:
