Early premium programs

Beginning in 1793, a U.S. merchant started giving out copper tokens which could be collected by the consumer and exchanged for items in the store. This practice caught on and was used by many merchants throughout the 19th century. Sweet Home laundry soap, a product of the B. A. Babbit Company, came with certificates that could be collected and redeemed for color lithographs

Tobacco inserts

Some of the earliest prizes were cigarette cards — trade cards advertising the product (not to be confused with trading cards) that were inserted into paper packs of cigarettes as stiffeners to protect the contents. Allan and Ginter in the U.S. in 1886, and British company W.D. & H.O. Wills

 in 1888, were the first tobacco companies to print advertisements and, a couple years later, lithograph pictures on the cards with an encyclopedic variety of topics from nature to war to sports — subjects that appealed to men who smoked. By 1900, there were thousands of tobacco card sets manufactured by 300 different companies. Following the success of cigarette cards, trade cards were produced by manufacturers of other products and included in the product or handed to the customer by the store clerk at the time of purchase. World War II put an end to cigarette card production due to limited paper resources, and after the war cigarette cards never really made a comeback. After that collectors of prizes from retail products took to collecting tea cards in the UK and bubble gum cards in the US.
Trade cards to trading cards

The first baseball cards were trade cards featuring the Brooklyn Atlantics produced in 1868 by Peck and Snyder, a sporting goods company that manufactured baseball equipment. In 1869, Peck and Snyder trade cards featured the first professional team, the Red Stockings. Most of the baseball cards around the beginning of the 20th century came in candy and tobacco products produced by such companies as Breisch-Williams confectionery company of Oxford, Pennsylvania, American Caramel Company

Ward: the father of mail order

By creating a direct marketing industry through his mail order catalogue, Aaron Montgomery Ward would unknowingly enable the creation of a powerful global network that would include everything from mailing, to mail order, to telemarketing and lastly to social medias. Together Ward and his [long time] competitor Sears changed the direction of the American marketplace by introducing the concept of individuality with the term consumption, allowing therefore the generations of today to take full control of their consumption behaviours and all of this in complete privacy. Today, the mail order catalogue industry Montgomery funded is worth approximately 100 billions of dollars, and generates over 2 trillion only in [incremental] sales and supports till this day an estimated 10.9 million jobs either directly related to marketing industry or dependent upon it.

 to draw upon the positive experiences of those exposed to loyalty business model inspired ventures to attract new customers. Fred Reichheld makes the point in his books that one can leverage the "power of extension" to draw new customers.

The rapid expansion of frequent-flyer programs is due to the fact that loyalty marketing relies on the earned loyalty of current customers to attract new loyalty from future customers. Incentive programs that are exclusive must strike a balance between increasing benefits for new customers over any existing loyalty plan they are currently in and keeping existing customers from moving to new plans. Hallmark did this through devising a program that directly rewarded customers not only for buying merchandise and utilizing Hallmark.com, but gaining additional benefits through referring their friends.

The most recent loyalty marketing programs rely on viral marketing
