Advertising firm, DDB Stockholm recently developed a campaign
for Volkswagen based on the belief that the best way to get people to make
positive changes in life, such as increasing physical activity and taking care
of the environment, is to make it fun. They call it "The Fun Theory".
The Fun Theory has commenced several experiments
to test the hypothesis.A WAHPSA
favourite is where they encourage people to take the stairs rather than the
escalator .
The Fun Theory website has many other great examples
that test the theory.
