Matichon is a major Thai-language daily newspaper founded by progressive writers in 1978, when Thailand was emerging from authoritarian rule following the October 6, 1976 Massacre. The newspaper positions itself as a quality, upmarket publication with a strong focus on politics, distinguishing itself from sensationalist mass-circulation papers. With a circulation of approximately 120,000 in 1997, Matichon became one of Thailand’s most politically influential newspapers alongside Thai Rath. Since the late 2000s, the publication has faced criticism for alleged pro-Red Shirt bias and controversies regarding editor dismissals and a bribery investigation by the National Press Council of Thailand, for which the paper resigned from the council in protest. The newspaper is owned by Matichon Public Company Limited and operates within the larger Matichon Group, which includes sister publications Khaosod and Prachachat Business. The company maintains both print and online operations, with Matichon Online having a separate editorial board from the print edition.
