South Korea says leaders in the North will pay the "corresponding price" for their suspected nuclear test Tuesday.
As part of the punishment, the South will resume propaganda broadcasts along the border this week -- an action that has riled the hermit regime in the past. There are several loudspeakers along the DMZ. Soon, those speakers will blast outside news to those patrolling the border in the North.
Though propaganda broadcasts may reach the ears of a few Northern soldiers, it's hardly the most efficient way to reach people on a large scale.

She says that groups outside of North Korea have found several ways to smuggle forbidden media into the country. This includes music, movies and even popular TV shows from the US and South Korea.
