Out-of-Home Advertising (OOH) refers to any advertising that reaches consumers while they are outside their homes. This includes billboards, transit ads on buses and subways, 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 to a broad audience. OOH advertising is often strategically placed in high-traffic areas to maximize visibility. It can be used to create brand awareness, promote events, or drive sales. With the rise of digital technology, many OOH ads now incorporate digital screens, allowing for dynamic content and real-time updates.
