A billboard is a large outdoor advertising structure (a billing board), typically found in hightraffic areas such as alongside busy roads. Billboards present large advertisements topassing pedestrians and drivers. Typically showing large, ostensibly witty slogans, anddistinctive visuals, billboards are highly visible in the top designated market areas. Bulletinsare the largest, most impactful standard-size billboards. Located primarily on major highways, expressways or principal arterials, they command high-density consumer exposure(mostly to vehicular traffic). Bulletins afford greatest visibility due not only to their size, butbecause they allow creative 'customizing' through extensions and embellishments.
