Rich Media
Display ads with interactivity beyond a click: expansion, video, forms, games, carousels. Rich media is built in HTML5, often by specialist studios or in creative management platforms, and served through ad servers that support the format's larger file weight and event tracking. The IAB's HTML5 guidelines govern file size and behavior.
