Korea changed its political system from authoritarian to a democracy. Under different political regimes, the media role is altered. In other words, ideology level affects the content of media. Also, depending on the regime type, a leader of a country may consider domestic audience costs differently when the leader makes a decision. This study examines how the two Korean newspapers, the Dong-a Ilbo and the Kyunghyang Shinmun, performed differently under authoritarian and democratic regimes especially during the Vietnam War, the Afghanistan War and the Iraq War using qualitative thematic content analysis. This study shows that the two newspaper changed coverage tendency. Under the authoritarian regime during the Vietnam War period in 1973, the two newspapers hold a more favorable view of the government and its policy and did not pose any negative opinions on government decisions although several articles revealed the critical analysis of the Vietnam War. On the other hand, during the Afghanistan War and the Iraq War era in 2007, the two newspapers clearly presented what they approved or opposed on government war policy with audiences reactions.
