Cadbury is using social media to figure out the best flavored chocolate bar for each person. In this case it analyzes your Facebook profile to match the offerings exactly to your tastes.
Says Cadbury, “Cadbury has created the world’s first flavour-matching social vending machine – introducing the ‘Joy Generator’! Watch chocolate lovers discover their true Cadbury Dairy Milk flavour personality match based on their Facebook likes and interests. Their personalised flavour match block is then automatically dispensed for free!”
