BRANDING: Client name or logo must be featured

CLICKTHROUGHS: Please provide with the initial ATOL submission to avoid a delay in the posting of your ad.

ADDITIONAL REQUIREMENTS: The Interscroller viewport should be designed as a transparent ad as the viewport area “floats” above the background. Logos, content and messaging appear on the viewport area while the background functions as a canvas to present that message. 

*SPECIAL NOTES: Unit will appear once per 12 Hours for viewers. The video will autoplay, but is muted and the audio must be user initiated with a tap or click. Most common video file types are accepted (MP4, MOV and WMV) and others may be converted to use (please allow for testing of other video types). Campaigns run a maximum of 4 consecutive days. Interscroller appears mid-article for all articles that are 2,000 characters or longer and have no related content embedded in the middle of the story.  For all other articles, the Interscroller will appear below the story text.
