Etymology

The word "billboard" combines "bill" (from Middle English bille, meaning a written notice or list) and "board" (from Old English bord, meaning a flat plank or surface). Originally, "bill" referred to official documents or advertisements, while "board" denoted a physical surface for display. By the 19th century, the compound "billboard" emerged to describe large outdoor structures for posting advertisements, reflecting the practical function of combining written notices with a visible platform.
