Chojoongdong (, CJD) is a coined term which refers to three highly circulated conservative newspapers in South Korea. The word is an acronym of the Chosun, Joong-ang and Dong-a Ilbo daily news, and was used by a Hankyoreh editor Jung Yeonju as early as October 2000. Korean liberals criticize Chojoongdong primarily because of their conservative-biased editorial stances and doing business in a collusive and surreptitious manner. Since 2008, some critics of CJD have claimed that there is a close relationship between CJD and the Lee Myung-bak government.
As of July 2008, the market share of Chosun, Joong-ang and Dong-a Ilbo is 25.6%, 19.7%, and 14.3% respectively; nearly 58% of printed newspaper subscribers in South Korea read one of the three daily news. In December 2011, Chosun Ilbo opened their own cable news network.
