Billboards remain the most popular outdoor advertising format by a wide margin. According to the OAAA, large-format ads accounted for 74.5% of total OOH revenue in early 2025, making them the go-to choice for brands looking for broad visibility along highways and urban corridors.
After billboards, transit advertising, street furniture, and place-based media round out the core format categories, with each suited to different campaign goals and audience environments.
Digital OOH is the fastest-growing segment within those categories, now representing about 34% of total spend. DOOH screens offer creative flexibility, real-time updates, and programmatic buying options that static formats can't match. Most high-performing campaigns layer multiple formats together.
With AdQuick, brands can browse inventory across every major format type, compare pricing by market, and build multi-format campaigns without coordinating across separate vendors.
