This article divides the types of magazines published in North Korea into 11 categories: (1) theory magazines, (2) popular magazines, (3) pictorial magazines, (4) current affairs magazines, (5) propaganda magazines, (6) liberal arts magazines, (7) children’s magazines, (8) magazines published by social groups, (9) literary magazines, (10) sectoral or specialized magazines, and (11) academic journals, and analyzes the publication status, contents, and characteristics of each. In terms of the publisher, North Korean magazines were published by groups of experts and intellectuals filling in the content, and in the early days, professional organizations or social groups took the lead in publishing magazines.

North Korean magazines would have been distributed systematically through distribution networks rather than targeting individual readers.
