BillboardsIn

BillboardsIn is an online out-of-home advertising marketplace operated by DOmedia and based in Columbus, Ohio. The platform lets advertisers search, compare, price, and book outdoor media across the United States and Canada, aggregating inventory from thousands of independent media owners into a single e-commerce experience. Buyers can browse billboards, digital displays, transit advertising, street furniture, place-based media, and other formats by market, then review availability, estimated pricing, and audience information before launching a campaign online.

The company positions itself as a tool that opens out-of-home to first-time and smaller advertisers, noting that a large share of its customers have never previously purchased a billboard. Media owners can integrate their inventory, pricing, and availability directly into the BillboardsIn catalog, where it also connects to the broader DOmedia enterprise platform used by agencies and larger buyers. Through partnerships with inventory and supply-side technology providers, the marketplace has expanded the number of assets available for online booking, reflecting growth in demand for self-service out-of-home buying.

BillboardsIn emphasizes transparency, ease of comparison, and streamlined ordering, aiming to remove friction from a category that has traditionally relied on direct negotiation with individual operators. By combining a consumer-friendly storefront with backend integrations for sellers, the company serves both ends of the transaction, supporting local businesses, agencies, and national brands seeking accessible entry into the out-of-home advertising market across North America.
