Ad Requirements

We are always looking to create new digital experiences
that entertain, inform, and connect.

The MSN Custom Header Ad takes advantage of the responsive design of MSN. An Advertiser can choose to display a single creative across all three page widths (2-, 3-, 4-column views), or can customize the creative for each of the page widths. The creative can re-animate on page resize, if desired. The user can hide the ad experience and then reopen it later, similar to the Billboard experience.
