A popular form of product and service promotion, an out-of-home advertising campaign refers to any advertisements placed on outdoor media, e.g. billboards, city lights, large-format mesh banners, LED displays, transit advertising and totem signs in shopping centres. Digital media, used primarily in the city centers of major cities, at bus stations or on the underground, with 10- to 15-second long ads played in a loop a few dozen times an hour, are becoming increasingly popular. Ads on outdoor media are usually large, noticeable and provide a minimalist and clear message that captures the attention of passers-by and motorists.An unquestionable advantage of this medium is its 24-hour availability.
