Media has had an important role in South Korea long before it became its own country in 1948. Throughout numerous periods of unrest and unconsolidation, the media market in Korea (before the seperation of North and South) always upheld and nationalist and independent tradition. According to a report by countrystudies.us:
"Many Korean journalists established a tradition of remaining independent. They were often critical of the government, zealously protesting any attempts at press censorship."
Media practices in South Korea have gone through many significant changes to become the dignified press that it is today. Modern media in Korea began in the late 19th century during the late stages of the Joseon Dynasty as journalists objected to Koreas isolationist dependence on China. The most important reformation came during the Japanese annexation of Korea in 1910, where the Japanese governer general assumed direct control of the press. It was the immense censorship of Koren publications that sparked the 1919 uprising known as the March 1st Movement, which was one of the earliest displays of resistance to Japanese rule. As a result, the Japanese government loosened their restrictions of the press. Many privately owned newspapers continued to adress issues of censorship and government control in their dailies. As reported by pressreference.com:
"Enlightening the public was the primary objective of the press. When Japan colonized Korea in 1910, privately owned dailies began to play the role of educators and independence fighters."
During World War II, all Korean publications were outlawed until Japans defeat and the U.S.'s occupation of the country in 1945. It was in 1948 that Korea had been split into two distinct countries, North and South. North Korea kept the tradition of state controlled media (under Russian influence), while South Korea constantly fought authoritarian powers trying to gain control of the press. From the day the country was granted independence up until the 1990's, authoritarian dictators attempted (many successful) to quiet the mouths of Korean journalists. This, however, did not stop them.
Today, the Korean press is among the most distinguished in the world. There are over 100 national newspapers including 2 english speaking newspapers, The Korea Times and The Korea Herald. The top 3 national newspapers have a circulation of 2 million people each. The television market has expanded greatly with the introduction of satellite broadcasting, and the percentage of internet users surpasses many other countries. It's the traditional ideology of South Korean media that has made the country a pioneer in that region for technology and the spreading of information.
