An advertising customer who pays to run ads on specific sections or pages of a site, to the exclusion of all other ads. These ads are given priority over all other ads, even targeted ads. Often these ads are messages that are integrated with your content on an exclusive basis, for example, transition ads with "brought to you by" messages. Both pages and targets can have sponsors. To set up this type of ad, use the Target Groups module and specify the sponsor action in a target expression.
