"Out-of-Home" (OOH) refers to advertising that reaches consumers while they are outside their homes. This includes various formats such as billboards, transit ads, and posters in public spaces. OOH advertising is designed to capture the attention of people on the go, making it an effective way to promote products and services. The OOH advertising industry has evolved with technology, incorporating digital displays that can change messages in real-time. This allows advertisers to target specific audiences based on location and time, enhancing engagement. Common examples of OOH include ads on buses, subways, and large billboards in busy urban areas.
