- In some cases, where Rich Media advertising is used – Sizmek can play the role of a fourth-party ad server (Rich Media Ad Server). The IAB defines Fourth-Party Ad Server in Appendix A of the IAB Rich Media Measurement Guidelines: A publisher website has an advertiser that wishes to use one of Sizmek's Commercial Break advertising implementations. The publisher hosts its own ad server. The advertiser's agency uses a third-party ad server (other than Sizmek) to coordinate all buys in one location.
In this case, the publisher would be considered the first party, the server that the advertiser's agency's uses to coordinate all media buys would be the third party, and Sizmek the fourth party.
