Censorship is a major theme of struggle in communist countries such as China and North Korea. Throughout the rest of the world and even in those countries, people write articles online about how the government suppresses the people. The government does not want citizens to find out about just how different the outside world is compared to their own country. These countries use censorship to block material they deem inappropriate. These materials may include books, embarrassing past events, or corrupt dealings such as scandals and bribery, something very common in communist countries.
