The beautiful thing about programmatic advertising is that it’s possible to serve ads in practically every country in the world (with the exception of - for example - North Korea).
An explanation: adexchanges have thousands of apps and mobile websites connected to them. These apps and mobile sites often have a global audience. For example Youtube or Gmail are publishers that are used in pretty much every country. With that; we can serve banners in every country.
It’s also possible to serve speficic ads aligned with specific moments on traditional TV. This can be specific commercials (f.e. from a competitor) and/or specific shows/actual television. Check out TVTY to learn more.
