Outdoor advertising[advertising?:advertising material cutting machine], also known as out-of-home (OOH) advertising, this is a broad term that describes any type of advertising that reaches the consumer when he or she is outside of the home.
Outdoor advertising is a mass-market medium, just like broadcast. It is better used for broad messages, branding and support campaigns. It cannot do the heavy lifting, and any attempts to do so will usually lead to a very cluttered and confusing message.
The most common forms of outdoor advertising include:
Billboard advertising
Point of sale displays
Street furniture (bus shelters, kiosks, telephone booths etc)
Transit advertising and wraps (taxis, buses, subways, trains etc)
Mobile billboards
Guerrilla advertising (also called ambient media)
