A company that brokers online advertising by bringing Web publishers and advertising buyers together on a Web site where they can participate in auctions for ad space. Set up in a Nasdaq-like exchange for the buying and selling of digital advertisements, an ad exchange is a marketplace where publishers and advertisers can find and execute advertising transactions (similar to what happens on a stock exchange).
An ad network also extends to text link ads where participating sites display text ads in exchange for credits which are then converted (using a predetermined exchange rate) into ads to be displayed on other sites.
