user-configurable advertising banners

clicking the trashcan icon removes the banner

Users generally prefer not to see ad banners, but if banners are mandatory (e.g. to keep a website free of subscription fees), users will typically prefer ad banners matching their interests over banners promoting undesired products. This creates an opportunity to make users cooperate with advertisers. User-configurable advertising banners are accompanied by a trashcan button. Pressing the trash can button lets the current banner disappear by replacing it with a different banner. The rejected banner and banners promoting related product types will not be displayed again.
