From newspaper coupons to personal discounts: the history of promo codes

The familiar "enter promo code" prompt is a descendant of the paper coupon, which is over a century old. Over the years, the coupon has survived the newspaper era, crises, and the advent of the internet, evolving into a personalized offer, compiled by an algorithm for a specific customer. We trace the history of coupons from the first paper coupons to discounts curated by a neural network.

The First Coca-Cola Coupon and the Coupon Mania of the 20th Century

The genre's history is traditionally traced back to the late 19th century, when Coca-Cola began handing out coupons for a free glass of the drink. The move proved ingenious: those who tried it returned for cash, and within a few years, the little-known soda became a national product. The trend was adopted by the entire American retail industry. During the Great Depression, clipping coupons from newspapers became a family savings ritual, and by mid-century, entire coupon sections appeared in the press, along with the first clearing companies, processing billions of coupons annually.

Even then, principles that have survived to this day were established: limited validity, "one coupon per customer," and a link to a specific product. The mediums have changed, but the logic remains the same.

The scale of the phenomenon by the end of the century was enormous: clearing houses processed coupons on conveyor belts, and newspapers competed with the thickness of discount inserts.

Coupons in the late USSR and 90s in Russia

In the Soviet economy, the coupon had a different role: coupons of the late 80s didn't provide a discount, but rather rationed scarcity—sugar, soap, and tobacco were rationed per capita. A related genre—the markdown—has survived all eras: is it worth the risk today for such a discount? promokodi.net He discusses this in a separate column. Discount mechanics in the Western sense arrived in Russia in the 1990s along with market trade: newspaper inserts, cut-off corners of advertising flyers, the first store discount cards. By the 2000s, discount coupons had become a common retail tool—all that was left was to wait for technology that would eliminate the need for paper.

The arrival of the Internet: code instead of paper

Online stores no longer needed paper coupons—they were replaced by a combination of symbols in a special field. The change in medium changed the mechanics:

• It became possible to distribute the code instantly and without a circulation - by mail, banner, social network;
• one-time and limited combinations with precise control appeared;
• The store saw which channel brought the customer, and the code became an analytics tool;
• Aggregator websites have emerged that collect codes from hundreds of stores in one place.

The RuNet has moved quickly: discount newsletters appeared alongside the first online stores, then a wave of coupon services taught shoppers to hunt for deals, and code aggregators turned the hunt into a familiar routine—open a catalog, copy, apply.

The Age of Marketplaces and Personalization

Marketplaces have complicated discounts: codes have been supplemented with points, cashback, subscriptions, and personalized pricing, and the "promo code" has become one layer of a whole benefit system. The modern "discounted price" is composed of several components:

• promotion of the site or seller for the product itself;
• promo code - general or personal;
• loyalty program points and cashback;
• paid subscription privileges.

At the same time, the discount has become targeted: algorithms analyze purchase history and issue offers to a specific person—a code for the category you were viewing, at the moment you're ready to buy.

What's next: discounts from neural networks

The next step in evolution is already visible: personalized discounts are compiled not by a marketer, but by a machine learning model. It predicts the discount size that will convince a specific customer, and doesn't waste budget on those who will buy anyway. For the buyer, this means a new reality: benefits depend less and less on luck and more and more on behavior predicted by the algorithm. Voice assistants are applying codes automatically, loyalty programs are merging with banking services, and the "one-size-fits-all" discount is gradually becoming a thing of the past—every customer has their own value proposition. The coupon has evolved from a newspaper clipping to an algorithm, but the essence hasn't changed: the seller pays you for your decision to try.

History lessons

The evolution of discounts is a change in medium, but the idea remains the same: a paper coupon, a printed insert, a digital code, a personalized algorithmic offer. Each era has made coupons more precise and faster. Understanding this logic is also useful in practice: a discount has always been a seller's tool, meaning it's most beneficial to those who use it consciously.
