List: Placement PositionsValue 13

When to send it

Value 13 extends the double box: content and ad sit in two boxes, and the advertiser's artwork also fills the space around and behind them. It arrived in AdCOM 1.0-202607 and is sent in Video.pos with a video plcmt of 8 (Squeezeback).

The background gives the advertiser most of the screen, so buyers usually need two assets, the box creative and a background image, plus the box geometry. It is confused with 12 (no background) and with 11 (Frame the content), where there is only one box and the ad forms the frame. Agree on asset specifications with the seller, because AdCOM does not define them.

Example

{
  "imp": [
    {
      "banner": {
        "pos": 13
      }
    }
  ]
}
