From Poster Panels to Electronic Displays
For more than a century, the billboard business depended on printing. From hand-painted advertising murals to multi-sheet poster panels to vinyl prints, outdoor advertising and commercial printing evolved together. Today, that relationship is beginning to unravel.
When Clear Channel Outdoor agreed in February to be acquired by Abu Dhabi-based Mubadala Capital and Chicago-based TWG Global in a $6.2 billion take-private transaction, the deal was widely framed as another step in the digital transformation of the out-of-home advertising business. The investor group highlighted Clear Channel’s network of roadside displays and airport signage as a platform for expanding electronic billboard infrastructure and data-driven advertising systems.
The combined funds’ interest in outdoor advertising is driven largely by the economics of electronic billboards. Once installed, a digital display can rotate multiple advertisements in rapid succession, dramatically increasing revenue per location while eliminating many of the logistical costs associated with traditional printed media. For operators such as Clear Channel, Lamar Advertising, and Outfront Media, converting static structures into LED billboards has become one of the industry’s primary growth strategies.
That transformation has been underway for two decades with the widespread introduction of LED displays. For the segment of the printing industry that supports outdoor advertisers, the implications are clear; every conversion of a billboard to digital technology replaces the many printed signs that would have been required over the coming years.
The Sign Painters
To understand the significance of this shift, it is worth recalling that billboard advertising itself has undergone several technological revolutions over the past century and a half.
In the early days of outdoor advertising, billboard graphics were not printed at all. Instead, they were hand-painted signs created by skilled artists who reproduced advertising imagery onto large wooden panels or painted directly onto the side of buildings. Sign painters often worked from small-scale illustrations, carefully enlarging the artwork across the billboard surface using grids or projection techniques.
Companies such as Foster & Kleiser, one of the pioneering billboard operators in the United States, helped popularize these early roadside displays, relying on teams of painters who traveled from city to city producing large advertising murals by hand. The company was the proving ground for several well-known muralists, artists, and illustrators. Most famously, the company’s artists hand-painted the iconic billboards on Los Angeles’ Sunset Strip, promoting rock-and-roll acts. (The company went through a series of name changes, sales, and acquisitions, and eventually disappeared into what is now Clear Channel Outdoor, the same aforementioned Clear Channel company.)
The 1889 Paris Exposition
In 1889, the French government sponsored the Exposition Universelle de 1889 in Paris to commemorate the centennial of the French Revolution. The fair showcased numerous technological innovations of the industrial age and introduced what would become the world’s tallest structure for more than four decades: Gustave Eiffel’s iron tower.
Less well known, but possibly more impactful on today’s visual landscape, was the display of a large multi-sheet advertising poster at the fair by the Morgan Lithographic Company of Cleveland, Ohio. The billboard, originally composed of 24 separate printed paper sheets, formed a coherent large image when aligned and pasted together. The company, well known at the time for its colorful printed posters for the Ringling Brothers Circus, won the gold medal for its vibrant, saturated chromolithographic posters. These were produced by stone lithography, layering up to a dozen or more colors. The size of the stones limited the size of the sheet that could be printed, which led directly to the multi-sheet format for billboards.
No less important than the limitations of using stones in the printing process, the ease of transporting and installing manageable-sized sheets quickly led to the widespread use of multiple sheets to create large outdoor advertising. Eventually, the stone litho process gave way to large-format offset presses capable of producing sheets of the required size. Billboard poster sets were printed, trimmed with overlapping bleed, collated with numbered sequences, and packed for distribution. Installers, traditionally called “bill posters,” would climb ladders and scaffolds, glue and smooth the sheets to form a single billboard-size image.
