The Great October Revolution in 1917 is ambiguously evaluated by historians as well as modern Russian citizens. Interest for the historical affairs is largely connected with the social issues of the present period. The attitude of Moscow young residents studied at the post-Soviet period (age group 15-30) to the 1917 Russian history became a subject of qualitative survey conducted by the authors in 2015. The method of focus groups discussion with projective techniques was used. The opinions on the place of the 1917 Revolution in the Russian history of the XX century and level of knowledge of events and their major actors are analyzed, It was revealed that young Muscovites consider the events of 1917 as most important and ambiguous. Their knowledge of historical persons of the period is fragmentary and incomplete. Special attention in the survey was given to the sources of information, which is important in the context of medialization of history. In addition to lessons, lectures and textbooks, important role belongs to online media, mass culture sources (movies, books, theatre, exhibitions, etc.), as well as to significant others.
