Following the 1979 Revolution, the authorities of the new regime imposed significant restrictions on the music industry and other fields of art and media in Iran. Later, by the late 1990s, Reformist president Khatami advocated more openness in terms of the policies on cultural activities. The Ministry of Culture and Islamic Guidance, which was formed in 1984, is responsible for monitoring and sanctioning music and other types of cultural industries within post-revolutionary Iran.
