In the digital and technological era, minority languages, especially those that are endangered, seem to be getting a new chance to survive. The report examines the support measures of activists for the Balkan-Romance languages in social networks, their initiatives to promote and use their languages not only in the virtual, but also in the real life. Facebook thematic groups (12 Aromanian, 2 Megleno-Romanian and 1 Istro-Romanian) testify to the viability of endangered languages in the modern world, despite the leveling trends of globalization. An analysis of the content presented in social networks allows us to get a general idea of the state of the minority Balkan-Romance languages at the present time, to notice the main trends in their promotion programs and draw conclusions about their functionality.
