Media and propaganda

I think media has important role to spread political propaganda. After Korean war, South Korean government supported directors to make anticommunism movie, especially against North Korea. Also some composers made music too. It wasn't just for pop music, also children's songs too. All of songs and movies are about North Korea and other communist countries are evil, we should fight against them until Korea becomes unity. So even people did not mean to watch or listen stuff about anticommunism, the people usually contacted anticommunism before they realized it's political propaganda.
In 1960s, there was Vietnam war, and many South Koreans volunteered for army. This time, Korean government used media to spread their propaganda, anticommunism. So it aroused many people to against communism. As a result, South Korean government could send many soldiers to the War. After 1980s, the government didn't make movies or songs to spread anticommunism. So young people don't hate communist countries, even North Korea or care about that countries.But old people still don't like communist countries, because they went through the era, when government brain washed people by media.
