DOOH, or Digital Out of Home, refers to the use of digital technology to display advertisements or other content in public spaces. This can include digital billboards, interactive kiosks, and screens in places like shopping malls, airports, and bus stops. Unlike traditional out of home advertising, DOOH allows for dynamic and targeted messaging, as well as real-time updates and data tracking. With the rise of digital media, DOOH has become an increasingly popular and effective way for brands to reach and engage with consumers in the physical world.
