The Evolution of Retail Displays: ​

From Hand-Painted Boards to Digital Visual Displays​

Retail signage didn’t start with digital screens. It started with painted symbols on Roman walls, ivy bushes nailed above tavern doors, and elaborate hand-painted boards that doubled as small works of art. The technology has changed dramatically over the last two thousand years. The job hasn’t: get people to stop, look, and walk in.

Here’s how retail displays got from there to here, and where they’re heading next.

Pre-19th century: hand-painted boards and the original visual language

The earliest retail signage goes back to ancient civilisations. Egyptians, Greeks, and Romans used painted symbols and terracotta plaques to advertise shops and services, and the Romans in particular were prolific about it. Taverns hung ivy bushes above their doors to signal wine. Bakeries used loaves. The whole vocabulary of “we sell the thing this picture shows” was already in place.

By the Middle Ages, hand-painted signs had become the standard in European trade districts. Most people couldn’t read, so the signs relied on imagery, and innkeepers in particular got creative: signs were elaborate, often humorous, and frequently the first impression a traveller had of a business. The craft of sign-painting required real skill, and good signs were considered a serious commercial asset.

Worth noting: the basic logic hasn’t changed. “Symbol that communicates what we sell, visible from the street, designed to interrupt the passing eye” is the same brief today. The materials are just different.

19th century: the printing press and the rise of consistency

Printing technology transformed retail signage by making it reproducible. The first known printed advertising poster came earlier than most people guess: William Caxton printed an advertisement for the Ordinale ad Usum Sarum, a priest’s handbook, in 1477. But mass adoption took another few centuries, and the real shift came in the 19th century when lithography arrived and made colour printing practical at scale.

For the first time, businesses could produce signs that looked identical across multiple locations. Brand consistency, which today is treated as a baseline expectation, was a new and powerful idea. Small businesses could now afford professional-looking signs that competed visually with bigger players, and storefronts started to look more designed and less improvised.

1920s to 1960s: the neon era

If the printing press standardised signage, neon made it impossible to ignore. The first neon sign in the United States was installed in 1923 in Los Angeles, advertising a Packard dealership. It cost $24,000, the equivalent of several hundred thousand dollars today, which is a remarkable amount of money to spend on a sign and also entirely explains why the technology spread the way it did.

Through the middle decades of the 20th century, neon defined the visual identity of urban retail. Bent glass tubes filled with different gases produced colours and shapes that nothing else could match, and entire districts (Times Square, the Las Vegas Strip, downtown Tokyo) became globally recognisable largely because of their neon. The signs weren’t just advertising. They became the architecture.

2000s to present: digital displays and interactive signage

The digital revolution changed two things about retail signage at the same time: what the sign could show, and how often it could change. LED displays, digital billboards, and interactive kiosks meant a single piece of hardware could run an unlimited number of campaigns, update in real time, and respond to the person standing in front of it.

That flexibility opened up possibilities that earlier formats couldn’t approach: dynamic pricing displays, time-of-day-specific promotions, interactive product browsers, personalised content driven by customer data. The trade-off is that digital signage requires ongoing management in a way a painted sign never did. A neon sign from 1955 still works if you replace the gas tubes. A digital display from 2015 may already be running on hardware nobody supports.
