The program of the glasnost period was distinguished by its fast tempo and the display of the countdown from 600 to zero.^[1] The anchor Nevzorov used the broadcast in order to criticize corrupt Soviet officials and promote preserving the Soviet Union (in the Baltic States, he is known as a fierce opponent of the national independence movements). Later – during the early Yeltsin years – the broadcast became a mouthpiece of Russian Nationalist opposition to Yeltsin's policies and was banned twice – definitively after Yeltsin's victory in his conflict with the rebel parliament.
