Outdoor advertising does not interrupt consumers in any way. There's no obnoxious sound, smell or other type of negative attention grabber. Billboards are noticed because of their messages, bright bold colors and creative graphics.
Outdoor advertising is the oldest and most basic type of advertising.
The average person must see a television commercial at least seven times before they actually remember viewing the commercial. Now think about the expenses.
Billboards are viewed 24 hours a day, 7 days a week by billions of different people.
