What type of advertising does OOH encompass?

Out-of-home (OOH) advertising encompasses public space placements, which include a wide range of advertising formats that reach consumers while they are outside their homes. This type of advertising typically includes billboards, transit advertising (such as ads on buses and subways), airport advertisements, and various other formats placed in high-traffic areas. The primary aim is to target consumers in locations where they spend time outside their residences, effectively capturing their attention during their daily activities.

The other choices refer to specific or narrow categories of advertising. Email advertising is a digital format targeting users through their inboxes, while print advertising is a subset that refers to printed materials such as magazines or brochures, which are not strictly classified as OOH. Television advertising, although it can reach a broad audience, is delivered through a screen inside homes rather than in public spaces. Thus, the broad and inclusive nature of public space placements best defines OOH advertising.
