Learning by Shipping | products, development, management…:It is interesting to know the credit card companies were the pioneers in harvesting the concept of "Junk Mail".
"Credit card companies became famous for the offers inside your monthly statement in the 1980s—little paper inserts with offers to buy custom return address labels, go on cruises, or secure other financial products. Like confetti they would fall out of the envelope. These were the very definition of ‘junk mail’. Then the companies began to use your previous purchase history to target these inserts. If you were paying attention then you realized that junk mail started to look less and less junky. This ‘feature’ turned into a fear that credit cards were selling your charging history to random companies."
