Which of these is an example of out-of-home media?

Out-of-home media refers to advertising formats that reach consumers while they are outside their homes. This includes a wide range of advertising formats that are typically displayed in public spaces, ensuring high visibility to a diverse audience. Posters represent a classic form of out-of-home media, as they are strategically placed in locations such as streets, transit stations, and malls, allowing for maximum exposure to people who are on the go.

In contrast, social media ads, podcasts, and email newsletters are all examples of digital or direct marketing methods that reach audiences primarily within their homes or through personal devices. These formats depend on digital access and are often targeted towards individuals rather than the broader public landscape. Therefore, the choice of posters aligns directly with the definition of out-of-home media, making it the correct example for this question.
