He is one of the key figures in the kremlin's military-patriotic propaganda. Since 2015, he has been the general producer of the federal military-patriotic TV channel Zvezda, controlled by the russian ministry of defense, and has been their propaganda mouthpiece. Yanovsky is directly responsible for the creation and promotion of content in support of russia's armed aggression against Ukraine, thus contributing to the formation of anti-Ukrainian rhetoric in the russian information space, spreading disinformation about russia's war of aggression against Ukraine, and the preparation of biological and chemical weapons for use against russia.
The Zvezda TV channel under the leadership of Yanovsky systematically spreads disinformation and manipulations aimed at discrediting Ukraine and its Armed Forces. The channel's programs actively exploit typical kremlin propaganda narratives about the "illegitimacy of the Ukrainian government," "the spread of neo-Nazism in Ukraine," and "the protection of the russian-speaking population." Particular attention is paid to justifying russian war crimes and missile attacks on Ukraine's civilian infrastructure.
Under his leadership, the TV channel created stories that justified russian crimes in Bucha and Mariupol and shifted responsibility for them to Ukraine. In particular, Zvezda TV channel actively supports the fake version of the events in Bucha, where the war crimes of the russian army were presented as a "Ukrainian provocation". Such information campaigns are aimed at undermining international support for Ukraine and justifying russian armed aggression.
The channel also actively disseminates propaganda theses about the "collective West" as russia's main enemy, and promotes ideas about the need to "denazify" Ukraine. These theses are synchronized with the kremlin's statements and serve as a justification for a "special military operation."
It plays an important role among the participants in the information war aimed at justifying the russian occupation and delegitimizing the Ukrainian government. His activities play a significant role in supporting the kremlin's information campaign aimed at creating justifications for the continuation of hostilities and undermining confidence in Ukraine's Western partners.
Yanovsky is a screenwriter of TV series, author of books on military and military-intelligence topics aimed at glorifying the USSR military, the armed forces and law enforcement agencies of the russian federation, dedicated to the confrontation with foreign intelligence agents, as well as historical topics covering the life and glorifying the exploits of "russian grand princes and kings" and the Primates of the russian Orthodox Church.
He was awarded the departmental medal of the ministry of defense of the russian federation "For Strengthening the Combatant Commonwealth", which is awarded in russia to military personnel and civilian personnel of the armed forces of the russian federation for achievements in the formation and implementation of state policy in the field of international military cooperation and military-technical cooperation of the russian federation with foreign states and international organizations, as well as other citizens of the russian federation and foreign citizens who assist in solving the tasks assigned to the armed forces of the russian federation.
As part of the awards ceremony for journalists at the all-russian public-state organization russian Military History Society, founded by putin in 2012, Yanovsky was recognized by former Minister of Culture Vladimir Medinsky for creating a historical film about one of the "great" russian princes.
