Door-to-door marketing goes under the door

I had the pleasure of running the ADT Security advertising account in the U.S. for many years. One of our effective tactical tools for the brand (and for the pizza guys) was the simple door hanger piece. I recall the instructions on these programs was explicit about NOT sliding the piece under doors. We took the blue 1's and zero's that form the ADT force-field of protection very seriously. ADT Chile and DDB went the more invasive route as demonstrated in the video. Hope the Chinese restaurants in New York don't see this. Pasar bien.
