Getting them young - when school children are targeted for data mining

MY introduction to brand loyalty by manufacturers and marketers began in 1976, the year I started formal education. At school, we children were occasionally given free biscuits, toothpaste, magazines and milk, including condensed milk that came in small pyramid packaging which I don't see anymore today.

During some events, like the school's sports day, every student was also given a coupon which would entitle us to a cup of cold, sweet Milo. To me then, it was the most delicious drink on earth! Once in a while, the people who dispensed the drinks would let us have an extra cup.
