North Korea may be known as the world's most secluded society, but it too has witnessed the rapid rise of new media technologies in the new millennium, including the introduction of a 3G cell phone network in 2008. In 2009, there were only 70,000 cell phones in North Korea. That number has grown tremendously in just over a decade, with over 7 million registered as of 2022. This expansion took place amid extreme economic hardship and the ensuing possibilities of destabilization. Against this social and political backdrop, Millennial North Korea traces how the rapidly expanding media networks in North Korea impact their millennial generation, especially their perspective on the outside world.

Suk-Young Kim argues that millennials in North Korea play a crucial role in exposing the increasing tension between the state and its people, between risktakers who dare to transgress strict social rules and compliant citizens accustomed to the state's centralized governance, and between thriving entrepreneurs and those left out of the growing market economy. Combining a close reading of North Korean state media with original interviews with defectors, Kim explores how the tensions between millennial North Korea and North Korean millennials leads to a more nuanced understanding of a fractured and fragmented society that has been frequently perceived as an unchanging, monolithic entity.
