Banners are a standard programmatic ad format used in almost every campaign. They are also the most widely-used format online, and therefore, have extensive reach to the audiences being addressed. Additionally, thanks to the availability of several targeting options, it is possible to address specific audiences.
Banners also support rich media, which makes them more attractive and reduces banner blindness.
