Censorship in North Korea is more thorough than anywhere.
Televisions and radios are hard-wired to receive only Government-controlled frequencies.
Mobile telephones were banned in 2004.
Access to the internet is banned. The designated North Korean web suffix ".kp" remains dormant.
Educated North Koreans have no understanding of developments in the outside world, or any understanding of how backward their country is.
The censorship is so total that when confronted with the truth they assume that it is all lies.
