Recreational Equipment Inc. (REI) has come up with a clever ad campaign using venn diagrams.

Though many of us remember using venn diagrams in grade school, REI has used it to their advantage to make a series of simple yet effective advertisements. As the company is a sports company, each of them have a winter sport theme to them, some of which including skiing or snowboarding. Though the intent of these ads is to appeal to the sports fans out there, you don't have to know how to ski to be able to enjoy its ingenuity and smart marketing strategy.

As Recreational Equipment Inc. (REI) demonstrates, sometimes it's in the simplest ideas that can be the most effective.
