CTS Main Channel is the flagshipfree-to-airterrestrial television channel of theChinese Television System network and is the third oldest free-to-air terrestrial television channel in theRepublic of China (Taiwan) afterTTV Main Channel andCTV Main Channel.

The origins of CTS Main Channel go all the way back to 1956 when theEducation Minister of theRepublic of ChinaChang Chi-yun proposed an educational television service that world be run by Taiwan'sMinistry of Education. Efforts to prepare the said television service began in 1958 when studio space was first allocated in the Ministry of Education's headquarters, and in August 1961, Education Minister Huang Chi-lu formally established Taiwan'sNetwork of Educational Television (NETV), which first went on air on February 14, 1962, nearly 8 months before TTV Main Channel began transmissions. NETV closed down on February 16, 1970, after it was purchased by theTaiwanese government forNT$1 billion, and in May 1970, Order 117 of theExecutive Yuan proposed the formation of a third television channel to succeed NETV.^[1] CTS Main Channel was eventually established on January 31, 1971, as a joint venture between Taiwan'sMinistry of National Defense and the Ministry of Education. The channel opened on October 31, 1971, the 85th anniversary of then-presidentChiang Kai-shek.^[2] On November 1, 1971, it started airing English learning classes two hours a day during the 6-8am period (repeated between 1:30 and 4:30pm).^[3]

On July 1, 2006, by virtue of the Taiwanese government's media reform law, CTS Main Channel was incorporated into theTaiwan Broadcasting System (TBS), the island state's consortium of public television stations, withPublic Television Service (PTS) as the other member of the group. The absorption calls for the transfer of the station's main studios from Taipei to Kaohsiung in a span of five years. It shall, however, be allowed to continue generating its income through traditional advertisements, and maintain its 60-40 entertainment-news programming mix like before.

Starting from January 20, 2015, some digital cable TV companies switched the main channel to high-definition broadcasts. On June 8, it started broadcasting in 16:9 format. On July 29, the National Communications Commission approved the application for upgrading CTS Main Channel to HD. On August 28, Chunghwa Telecom’s MOD was upgraded to high-definition broadcasting (originally scheduled to be upgraded on September 1). At 5 a.m. on October 1, the terrestrial signal was upgraded to high-definition (HD) broadcasting, becoming the second terrestrial TV station to change its main channel to high-definition broadcasting.^[4]

CTS Main Channel is currently engaged in a campaign to restore its title as "Taiwan's drama authority", for having been home to some of Taiwan's most unforgettable drama serials.
