A Floating creative is a SWF that floats on top of a publisher’s page. It's also known as an interstitial or prestitial ad. This ad format allows flexibility. Because it isn't assigned to a fixed ad slot, it can be almost any shape or size, and you can place it anywhere over a publisher's content.
This guide walks you through the process of building a Floating creative using DoubleClick Studio components in ActionScript 3.
