Billboard Advertising
Posters are the other common form of billboard advertising, located chiefly in commercial and industrial areas on primary and secondary arterial roads. Posters are a smaller format than bulletins and are viewed principally by residents and commuter traffic, with some pedestrian exposure. Billboard advertisements are designed to catch a person’s attention and create a memorable impression very quickly, leaving the reader thinking about the advertisement after they have driven past it. They have to be readable in a very short time because they are usually read while being passed at high speeds. Thus there are usually only a few words, in large print, and a humorous or arresting image in brilliant color.
Some billboard designs spill outside the actual space given to them by the billboard, with parts of figures hanging off the billboard edges or jutting out of the billboard in three dimensions. An example in the United States around the turn of the 21st century were the Chick-fil-A billboards (a chicken sandwich fast food chain), which had three-dimensional cow figures in the act of painting the billboards with misspelled anti-beef slogans such as “frendz don’t let frendz eat beef.”
Many groups such as Scenic America have complained that billboards on highways cause excessive clearing of trees and intrude on the surrounding landscape, with billboards’ bright colors, lights and large fonts making it difficult to focus on anything else, making them a form of visual pollution. Other groups believe that billboards and advertising in general contribute negatively to the mental climate of a culture by promoting products as providing feelings of completeness, wellness and popularity to motivate purchase. One focal point for this sentiment would be the magazine AdBusters, which will often showcase politically motivated billboard and other advertising vandalism, called culture jamming.
In 2000, rooftops in Athens had grown so thick with billboards that it was difficult to see its famous architecture. In preparation for the 2004 Summer Olympics, the city embarked on a successful four-year project demolishing the majority of rooftop billboards to beautify the city for the tourists the games will bring, overcoming resistance from advertisers and building owners. Most of these billboards were illegal, but had been ignored up to then.
In 2007, São Paulo, Brazil instituted a billboard ban because there were no viable regulations of the billboard industry. Today, São Paulo, Brazil, is working with outdoor companies in the region to rebuild the outdoor infrastructure in a way that will reflect the vibrant business climate of the city while adopting good regulations to control growth.
