Using nationality names tends to be inappropriate for the media of ethnic minorities, and is prone to confusion with eponymous languages, especially in an area working with language. For example: TRT Kurdî perfectly fits in Category:Television stations in Turkey, and it would fit in Category:Broadcasting in Turkey, but does it fit in Category:Turkish broadcasting? Less so. Or how about private, Catalan-language station RAC 1? This clearly is broadcasting in Spain, but is it Spanish broadcasting? Clearly in terms of being located in Spain and being under Spanish jurisdiction, but less so in terms of "Spanish culture" and certainly not in terms of Spanish language. Let's be more precise here and use the country names rather than nationalities.
