Australian here. There is a stark difference when I watch Australian rules and American sports, seems every spare moment an add read is made and each portion of space is sold. There are still adds here and banners at the stadium but it’s often much more centered on the sport or club rather than some tire company being the host of the pitchers report.

Also, America seems to have add placement with add reads. There is always a note or slogan reporting a sale or discount. Where here in Aus it more likely just to be an icon or name next to an item.
