Laffichage

L’affichage, often written l’affichage in French, designates the act and practice of presenting information publicly or on a device so that it can be seen by an audience. It encompasses physical signage, posters, and notices as well as digital displays and screens. The term can refer to outdoor advertising, institutional notices, or the display of data and content in software and on information kiosks.

In common use, l’affichage is divided into several domains. Affichage publicitaire covers posters and billboards intended to promote products or events in public spaces. Affichage institutionnel refers to notices and information posted by governments, organizations, or businesses for public consumption. In digital contexts, affichage describes the rendering of content on screens, including electronic signage, information displays in transit, and user interface presentation of data. The concept also encompasses the display of results, messages, and alerts in various systems.

Historically, affichage evolved from printed posters and handbills in urban environments to sophisticated digital signage. The rise of printing technologies in the 19th century expanded the reach of posters, while the late 20th and 21st centuries brought electronic displays, LED billboards, and networked signage that can convey dynamic content.

Regulation and standards around l’affichage vary by jurisdiction but commonly address visibility, safety, zoning, licensing, and sometimes content restrictions. Municipal planning rules often govern where signs may be placed, their size, and lighting to balance information access with urban aesthetics and public space management.
