False information and no information to people in a country (ala the old Pravda in the USSR) as a means of achieving a politically repressive end is coming to a close.
Cuba, Ukraine and Venezuela are the proving grounds to show that governments can no longer keep the free will of the populace from exerting itself.
But the old dictators will hold on until they are thrown out. It could still take decades in some places where the dictatorship is effectively run by the military and they are the true power, like N. Korea.
The trend of history is clear over the last 150 years as countries have moved to freer and freer elections. The king is dead.
