It was gratifying to learn that my favourite delicacy as a child, caramel-coated popcorn called Cracker Jack, is still being sold. Each box had a prize at the bottom: miniature animals, whistles and the like. As a somewhat precocious child, and therefore I suppose not altogether likeable, I quickly figured out the art of opening the box at the nether end for immediate access to the surprise. However, times change, and instead of a prize at the bottom, from now on there will be a sticker with each box, meant to be scanned. The senior director of marketing for the company that makes Cracker Jack has announced that by downloading an app and scanning the sticker, one can “enjoy baseball-inspired mobile digital experiences”. No more plastic toy animals and tin whistles.
