Digital Outdoor (DOOH, Digital Out of Home) is advertising on digital screens in public space: LED billboards, screens in shopping centres, at bus stops or on public transport. Unlike classic OOH, the content can be changed remotely and adapted, for example to the time of day, the weather or traffic levels. It is increasingly bought programmatically, which brings planning outdoor advertising closer to the logic of digital. (Compare: OOH, Programmatic Advertising)
