Families that can afford them often have two TVs, according to New Focus International, a website that features dispatches from North Korean exiles; one TV is pre-set to state channels airing propaganda, while the second, illegal set is used to watch South Korean TV programs. Even so, fluctuating voltage in the electrical current often causes the screen to keep changing size, "going from big to small repeatedly," according to one exile report. Some of the most popular contraband items are DVDs of South Korean TV shows, which North Koreans often trade or sell among themselves.
