We all know what billboards are and cannot really miss them as many of them are large and colorful in order to catch our attention. They are all over the place, on streets, highways, shopping centers in most places where there is a high affluence of people.

The main objective of billboards is to grab the publics attention and make the reader ponder over the image or promotional message on the billboard long enough to persuade a person to buy the product or service advertised.

If you have decided to have a billboard installed somewhere public you should make sure that people can catch your message in a few seconds if you want your advertisement to be effective. The people reading your billboard will usually be driving or busy shopping if you have placed it inside a shopping center, this is why your message must be brief and concise even funny as well as colorful, in order to attract as much attention as possible.

Your billboard can be a common poster located in a commercial district or either on main or secondary roads. If your billboard is smaller in size make sure you have it located where the traffic is slower and pedestrians are more numerous.

Billboards are also effective on a subliminal level for they are aimed at the people that are found in consumer market areas and public places, which can be shopping centers, doctors offices or other similar public places.

However billboards can have some disadvantages as regards to public opinion. There are people who consider billboards as hazardous, especially on a road with a high density of traffic, such as highways or crossroads. They distract drivers attention and may cause car or pedestrian accidents. People also complain that trees have been cut down in order to place billboards for advertising, which renders them unpopular to the public. They are also considered as a form of pollution with their garish colors and bright lights, a disturbance to the aesthetic harmony of the setting.

Although they do have these disadvantages they still are one of the best ways to advertise. Some billboards offer digital signage and are placed in public areas with an electronic display, used for both indoor and outdoor purposes. This digital signage technique is used as a means of entertaining and is easier to change as far as images, texts and animations are concerned. These electronic billboards can be adapted to the type of public present on the premises and ever according to the hour of day.

Digital billboards can consist of scrolling messages or images, plasma displays, LCD, projection screens or electronic billboards. They are monitored electronically by a computer or similar device and images can be changed by remote control according to the need.

These billboards of the new generation are no longer as expensive as they used to be, for plasma and LCD prices have lowered considerably and Internet connectivity has made digital signage easier than it was in the past.
