2. Outdoor advertisements

Outdoor advertisements, or out-of-home advertisements, are the kind consumers see when they're outside their homes. Some businesses set up events in outdoor venues to promote their products, such as offering food samples or hiring people to dress in costume and distribute flyers. Other common outdoor advertisements include billboards and ads in the following places:

• 
  Highway sidelines
  
• 
  Building facades
  
• 
  Bus shelters
  
• 
  Cars or buses
  
• 
  Park benches
  
• 
  Movie theaters 
  

The key to successful outdoor advertising is being able to capture people's attention quickly with a message or image that they're likely to remember. A billboard, for example, may function best when it can communicate its message in a clear and interesting way in just the few seconds that a driver might look at it before driving onward. A poster-sized advertisement in a bus shelter might benefit from being memorable so a person won't forget it while they're on the bus or at home.
