Smartphone Interscroller

The Interscroller is an inline interstitial ad format. The content comes into view as the user scrolls the publisher page. When 85% of the placement is viewable, the content will “snap” to takeover the entire viewport. The user can scroll out of the screen view to dismiss the ad.
