One of the defining traits of the Dual Monarchy was the sheer number of different ethnic groups contained within its borders, with neither of the two largest single groups of the state comprising more than a weak plurality of its population (Germans at ~23%, Magyars at ~20%). Coupled with the state's nearly unbudging attitudes towards expanding freedoms to its minorities and only mediocre infrastructure and modernization at the time of its collapse, and the Empire was in comparison to other world powers at its time an unstable patchwork of ethnic unrest.
With this in mind, what might we see today in terms of the cultural and linguistic identity of the Austro-Hungarian Empire had it survived the early 20th century and undergone full modernization, in the process undergoing the age of mass culture and communications? In many other cases (particularly in France, wherein regional tongues pervaded across much of its territory very strongly until the early 20th century), the arrival of radio and television did much to spur the rapid homogenization of regional culture to that of the nation's metropolitan centers. Given how Austria-Hungary operated with regard to its non-Germans and non-Magyars (particularly with regard to the Magyarization programs strictly enforced in the Kingdom of Hungary), would this act as a means by which the state could more effectively assimilate its minorities, or a way for larger-scale nationalism to resist such efforts (i.e. foreign Serbian and Polish programming serving as an anchor for Serbs and Poles in the empire to retain their culture)?
The PoD here is not particularly specific, so long as it involves the Austro-Hungarian state surviving into at least the latter half of the 20th century (ideally to the present, though if this is infeasible than at least a 1960 cutoff will suffice). For simplicity's purposes let's assume a rapid Central Powers victory early in WWI (Miracle on the Marne doesn't happen and the Entente is forced to peace out early), with Germany then serving to prop up the Dual Monarchy to keep it stable.
