Those near the border who choose to stay away from the banned media from the flash drives often cannot escape it. Ever since the 1950s, both countries have blasted their own propaganda across the DMZ: North Korea broadcasting anti-south propaganda and South Korea broadcasting Korean and world news as well as K-pop. In 2004, both countries agreed to end the broadcasts. After an incident in 2015, South Korea resumed broadcasting anti-North news for four days, as well as in 2016, after North Korea tested its hydrogen bomb and has been broadcasting since. In April 2018, in preparation and out of respect for the meeting between North leader Kim Jong Un and South leader, Moon Jae In, the South Korean speakers ceased their broadcasts. These 11 loudspeakers can be heard up to six miles into North Korean territory. This enables the broadcasts to influence possible defectors staying near the border as well as create bothersome propaganda that North Korean soldiers cannot escape.
