What is it:
Interstitials appear on top of an AARP.org page right after the page load is complete. This high impact ad unit is served once a day to every unique visitor. The ad will auto-collapse after 10-seconds if no user interaction (e.g., un-mute) has taken place. If the user has interacted with the ad, the ad can remain in place until the user closes it. Creatives that use animation or video longer than 10 seconds run the risk of the user not seeing the media in its entirety. Backup images are not applicable for this premium ad unit.
