Lithography, developed in the late 18th century, allowed for detailed and colorful prints, enhancing the visual appeal of signs.

Urbanization and Commercialization

As cities grew and commerce expanded, the demand for effective signage increased. Businesses needed to attract the attention of passersby in crowded urban environments. This period saw the rise of large, bold, and brightly colored signs designed to stand out amid the urban hustle and bustle. The use of gas and later electric lighting in the 19th century revolutionized signage, allowing signs to be visible at night and further increasing their impact.

The 20th Century: The Age of Neon and Plastic

The Rise of Neon Signs

One of the most iconic developments in 20th-century signage was the invention of neon lighting by French engineer Georges Claude in 1910. Neon signs, with their bright, colorful glow, quickly became popular in major cities around the world. They were especially prevalent in places like Times Square in New York City and the Las Vegas Strip, where their vibrant illumination transformed the nighttime cityscape.

Plastic and Mass Production

The post-World War II era saw the introduction of new materials and mass production techniques that further revolutionized signage. Plastics, particularly acrylic and polyvinyl chloride (PVC), became widely used due to their durability and versatility. These materials allowed for the creation of lightweight, weather-resistant signs that could be produced quickly and affordably. This period also saw the rise of standardized signage for corporations and franchises, contributing to the uniform appearance of brands across multiple locations.

The Advent of Digital Technology

In the latter half of the 20th century, digital technology began to make its mark on signage. The first digital signs, using light-emitting diodes (LEDs), appeared in the 1970s. These early digital displays were limited in their capabilities but represented a significant step toward the dynamic, programmable signs of the future.
