Billboard advertising is a large-size outdoor advertising space aimed at capturing the attention of passers-by. It is usually placed in high traffic areas, near traffic routes and motorways, or, more recently, in sideways and pedestrian zones proximity. If placed in the city, it is usually at its busiest loops.
The most important element of billboards is that they transfer the short form message that can easily appeal to passers-by. Although it bears a poster resemblance, billboard advertising has the advantage of a larger size with reduced and effective message.
