radio transmissions in russia were money shot for aum, and idk if it was a fluke or deliberate strategy. people had for a long time expectation that radio and tv are authoritative, reliable sources (due to censorship that doubled as fact-checker, and about all of it was state-owned) and in 90s every bit of that broke down because of privatization, and now you could get on the air and say anything, with many taking that at face value, as long as you pay up. at the same time there was major economic crisis and cults prey on the desperate. result?

Following the sarin gas attack on the Tokyo subway, two Russian Duma committees began investigations of the Aum -- the Committee on Religious Matters and the Committee on Security Matters. A report from the Security Committee states that the Aum's followers numbered 35,000, with up to 55,000 laymen visiting the sect's seminars sporadically. This contrasts sharply with the numbers in Japan which are 18,000 and 35,000 respectively. The Security Committee report also states that the Russian sect had 5,500 full-time monks who lived in Aum accommodations, usually housing donated by Aum followers. Russian Aum officials, themselves, claim that over 300 people a day attended services in Moscow. The official Russian Duma investigation into the Aum described the cult as a closed, centralized organization.
