The population has little or no exposure to foreign cultural influences apart from performances by song-and-dance groups and other entertainers brought in periodically for limited audiences. These performances, such as the Spring Friendship Art Festival held annually in April, are designed to show that the peoples of the world, like the North Koreans themselves, love and respect the country's leader. During the 1980s and the early 1990s, the North Korean media gave Kim Jong-il credit for working ceaselessly to make the country a "kingdom of art" where a cultural renaissance unmatched in other countries was taking place.
