The work is devoted to the study of the features of the historical memory models formation in digital space using contemporary information and communication online technologies as an example of the Second World War. It analyzes the current practice of digital "memory wars" and the mechanisms of rewriting history on the Internet. The article shows that the extraterritorial nature of online communications allows carry out external information aggression into sovereign national segments of the Internet with the aim of transforming traditional historical codes, symbols, and meanings, as well as changing the mass perceptions of network users about the events of World War II. The author concludes that the availability of digital information and communication infrastructure, distribution channels of historical information, subjects of generation, and broadcasting of historical content is a key factor in ensuring the survival of national models of historical memory in a competitive digital space. Otherwise, they are replaced by alternative models that change the mass representations of network users, which leads to corresponding changes in the assessment of historical events and the rewriting of history in the framework of the global "memory wars". The paper also substantiates that the main target audience of information and communication work in the Internet space is the young generation, which will be the key carrier of historical memory models in their societies in the future. In this regard, the impact on the processes of forming ideas about the historical events of online users, the transformation of the attitude of young people to their national and world history, potentially make it possible in the foreseeable future to carry out a total rewriting of historical memory at the global level in the case of absence of the corresponding activity of states to protect their own national information spaces and counteracting external information and communication aggression.
