Domino's Pizza in the Netherlands launched an interesting campaign which not only serves to increase day-to-day sales and get consumers to see a new side of the long-standing fast food delivery category, but also contains the all important viral element as well as PR-value.
The pizza chain simply installed white doors featuring delivery phone number and equipped with doorbells for the delivery people to ring in a public space - thereby allowing modern consumers to satisfy their need for instant satisfaction right there and then.
A fantastic example of a simple idea based on a relevant consumer insight.
