A billboard (or billing board) is a large sign displaying advertisements. They are usually placed in places where many people will see them, such as alongside busy roads or in marketplaces. They show large posters, bulletins, and other kinds of visual advertisements.
Billboards that are along roads are designed to be noticed, since they are seen for only a few seconds. They usually have only a few words on them. Sometimes they have a humorous picture on them. For example, Chick-fil-A billboards have cows trying to get people to eat chicken.
Kinds of billboards
Painted billboards are made usually by hand. They are painted onto large pieces of paper, which are then attached to large panels. The panels are then installed using cranes.
Digital billboards use large screens to show the advertisement. Some digital billboards can change their message every so often, so several advertisements show up on the same billboard.
Some of the earliest billboards were made in the 1880s. In the early 1900s, many people in the U.S. were buying cars like the Ford Model Ts. During this time, it became popular for businesses to put billboards along highways.
