On May 25, 2010, South Korea responded to the alleged North Korean sinking of a navy ship by broadcasting 4Minute's single "HuH" across the DMZ. In response, North Korea affirmed its decision to "destroy" any speakers set up along the border. That year, "The Chosun Ilbo" reported that the Ministry of National Defense had considered setting up large TV screens across the border to broadcast music videos by several popular K-pop girl groups such as Girls' Generation, Wonder Girls, After School, Kara and 4Minute as part of "psychological warfare" against North Korea.
