Robert Jessup says on his blog:
“Street advertising, which has also come to be known as, or called ‘out of home’ (OOH) advertising, is a broad term used to describes any kind of marketing campaign that uses advertising techniques to reach consumers when they are outside, away from their home.
Street advertising can be accomplished virtually in any outdoor place, such as promotional paraphernalia at sporting events and musical concerts, billboards throughout cities, or simple signs outside on the street. Outdoor advertising can be compared to broadcasting methods, because both represent a type of mass-market medium, meaning that the intention of both are to reach a large, undifferentiated segment of the population (consumers) with indistinct and varied backgrounds.
Street advertising is best utilized through broad message advertising mediums, as well as branding and support campaigns”.
