There is plenty of attention factor in a blimp – you will automatically turn your head, look up, because you just have to see what is on the advertising blimp. Do you know the situation?
Use a helium blimp if you want to draw particular attention to your business eg at a grand opening or at a particular campaign.
The blimp is visible from great distance and works not only as floating advertising, but also as a guide or direction marker to your store.
And if the game is broadcast on TV, you will most likely also get your share of on-air time when the TV helicopter pan over the stadium, filming your helium blimp.
