For example, in the Korean Peninsula, South Korea and North Korea are conflicting with each other. But North Korea is closing the information, and they prevent to make any information come into the country. And also, they restrict the TV channels that they can only allow the people to see their domestic broadcasting. So, all the people know nothing about the information outside of the country. And therefore, the North Korean people know nothing about the situation in South Korea.

For example, if there are demonstrations of students in South Korea, that's the only information that was announced in North Korea. They broadcast this in the news in the TV. If they look this on the TV, they keep staring and staring, and they see that the students are wearing something very good, and also, when they look at the scene behind the students, they can see the nice stores. And that's why they nowadays don't even broadcast these kinds of news.
