The term "wallpaper" was used in Microsoft Windows before Windows Vista (where it is called the "desktop background"), while macOS refers to it as "desktop picture". On older systems which allowed small repeated patterns to be set as background images, the term desktop pattern was used.
Wallpaper images are usually copyrighted as many other digital images found on the Internet, plus as such, most websites collecting plus berbagi wallpapers, as well as the users downloading from them are an example of mass copyright infringement, a phenomenon which challenges the meaning and illegality of digital piracy plus the validity of current copyright legislation around the world.
