This is a native video solution designed to deliver rich mobile experiences and drive brand advertising effects.

StreamView begins to play when 50% or more of the ad is viewable. The video will begin playing muted, and within the dimensions of the ad itself. If the user scrolls further down the page (or back up), and the StreamView is no longer 50% viewable, then the video will pause, resuming when it is more than 50% viewable. If a user interacts with the StreamView then the video will open in full screen, and continue to play at the point it was at, with the audio on.

  Instantly captures users attention
  Viewable guarantee
  A great story telling format without any interactions needed
  Optimize view time
  Proven to drive maximized brand uplift
  Logo for added brand exposure
  Call to action link to strengthen message clarity
