How does the Phorm system work with the portal advertising that the ISP already receives?
An ISP’s portal site is treated just like any other publisher that participates in Phorm Open Internet Exchange (OIX). When an OIX-generated ad is of higher value than the current ad being served on the ISP portal, the OIX ad is served instead. Ultimately, the revenue generated from this and all the other ads served is shared between the ISP, the website serving the ad, and Phorm.
