Outdoor advertising is the world’s oldest form of public media. Billboards and other out of home (OOH) formats can be used effectively for a wide variety of products and services. Out of home advertising reaches people on the go no matter how they consume their media. As part of a marketing plan, OOH is proven to extend reach, amplify a campaign, and drive consumers to engage with brands. With an extremely low cost per impression and a high return on investment, outdoor advertising can deliver targeted audiences, and will enhance both social media and mobile marketing efforts.
