Synonym discussion
Sense: noun/1
All four words name a flat surface that carries a public message, but they differ in size, location, and region. A 'billboard' is large, outdoors, and almost always carries paid advertising — typically beside a highway or on the side of a tall building. 'Hoarding' is the British English word for the very same object; an American calls it a billboard, a Briton a hoarding. A 'poster' is much smaller, often paper, and can hang indoors (on a wall, in a shop, in a station) — it may advertise but can also announce a concert, lecture, or political message. A 'signboard' is the most general term: any board displaying information, including shop names or directions, not necessarily advertising. So a shop's name above its door is a signboard; a movie ad on Highway 5 is a billboard; the same ad on a corridor wall is a poster.

Etymology
Formed in mid-19th-century American English from 'bill' (meaning a printed public notice or poster, a sense going back to Latin 'bulla' through Old French 'bulle') plus 'board' (a flat wooden surface). A billboard was first simply a board on which paper bills were pasted up. The verb sense (to promote loudly) developed later in the 20th century, treating the noun as something one could do to a product.
