Out-of-home or OOH advertising refers to exactly what the name suggests – advertising you see outside the home.
This could be anything from a billboard on a major roadway, to a wallscape attached to the side of a city structure, to a poster at a train station, airport terminal, or kiosk. OOH also includes branded merchandise and apparel. In recent years, OOH has been evolving from static printed ads to dynamic digital formats, including video.
