Microsoft Loft


Loft provides advertisers with an always in-view solution. This unit spawns out of a traditional leaderboard banner unit (728x90, 970x250).  When a user scrolls down the page, Loft will render from the bottom of the user’s browser window.  The design is minimal enough to not interfere with the consumers experience and ability to consume content but large enough to send a powerful brand message.  Loft offers user click-to-expand with additional functionality including video, photo galleries, mapping, and more.
