Why does balloon advertising work so well?

Balloons draw attention.

People the world over like Hot Air Balloons. When a balloon is in the sky or on the ground it will always draw a crowd of people. Even the inflation of a balloon for a private flight will draw a small crowd. If you are at a large ballooning event, tens of thousands of people will see your balloon. If there is media coverage, which is often the case at many events, the numbers seeing your balloon increases beyond belief. A hot air balloon creates excitement that attracts and holds attention. It is just one gigantic, colorful, living, moving billboard.
