Abstract: A method includes, but is not limited to any combination of: determining a plurality of third-party content elements based in part on information associated with a request for third-party content. The request for third-party content may be received from a web browser displaying a first webpage to a user. A first element from the plurality of determined third-party content elements is transmitted to the web browser. Upon receiving from the web browser a second request for third-party content including user interaction data with the first element, data associated with the determined plurality of third-party content elements is updated based at least in part on the user interaction data. A second third-party element from the plurality of updated third-party content elements is transmitted to the web browser.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for interstitial content item revenue sharing. In one aspect, a method includes identifying an interstitial content item that was presented during a particular device session; identifying two or more participating resources that were requested during the particular device session; determining that two or more different participating publishers are associated with the two or more participating resources, each participating publisher being a publisher that has been approved to receive revenue for presentation of interstitial content items; and assigning a revenue share value to each of the two or more participating publishers, each revenue share value specifying a portion of interstitial revenue that the participating publisher is allocated for display of the interstitial content item.
