Billboard/Outdoor Advertising meaning and definition (in 100 words).
A Billboard (hoarding in UK) is a large outdoor advertising platform. The word is called so because the board is billed to advertiser. Located strategically on high traffic areas, highways, expressways or principal arterials, outdoor advertisements are more about witty slogans and visuals and less text compared to typical print ads.
The aim of such ads is to create memorable impressions very quickly because drivers are passing by at high speed. The ad should leave the readers ponder about even after they driven past it. Pros are they cost less and have good repeat value, cons are limited demographic exposure.
