Variations in local media systems have a high explanation value when it comes to trans-national differences between local adaptations of international formats. On the basis of four case studies of the local adaptations of the formats Ground Force, The Block, Nerds FC and Idol in Denmark and Australia, I will give concrete examples of media systemic explanations for some rather significant differences between the adaptations of the two countries, which may kick-start a discussion of what levels of a given local culture have more/most weight in the so-called" glocalisation" processes taking place on local television screens around the world. Thus, the chapter provides hands-on examples on how local producers in the two countries enter into very complex negotiations with the original, globalised format sources in order to localise the adaptations properly.
