The evolution of Loyalty Programs -how they started  -how's it going

Around the 19th century, the Americans handed out copper tokens to their customers which could be redeemed for products in the future.

The first retail loyalty program (stamp based) was the “Green shield stamps”. Those stamps could be used to redeem for catalog products.

Betty Crocker introduced coupons in 1929, which were directly printed on the product's packages & could be redeemed later.

The American Airlines’ frequent flier program is considered to be the first fully-scaled loyalty program of modern times.

The loyalty programs have  come quite far- from copper tokens and stamps to cashback and miles.
