MCOT Public Company Limited (MCOT) (Formerly known as the Mass Communication Organization of Thailand (M.C.O.T.)) (Thai: บริษัท อสมท จำกัด (มหาชน) (บมจ. อสมท), is a Thai state-owned public broadcaster. It owns and operates a number of radio and television stations in Thailand. It is based in Bangkok. At present, MCOT runs seven national, one international, 52 provincial, one district radio station, two television channels (terrestrial free-to-air), and 2 satellite television channels. Their motto is ก้าวไกลรับใช้ประชาชน ("Always Serving the Public"). On their website MCOT uses the slogan "Digitally beyond" (Nov 2014).[1] MCOT's acting president is Mr Piset Chiyasak.[2]



On 10 November 1952, MCOT was established as Thai Thorathat company limited. "Thorathat" means "television" even though there were no television services in Thailand then. Television services under the name Thai Thorathat (Channel 4) started on 24 June 1955 in time for national day celebrations.

In 1977 TTV Radio and Thailand Color Television Channel 9 moved to the present Huai Khwang headquarters in Bangkok and merged to form the Mass Communication Organization of Thailand (MCOT). In 1970, with the launch of Chong Sam (Channel 3), its newest station, while the original Thai Thorathat (Channel Four) network was renamed Chong Kao (Channel 9).

Witthayu Tor Tor Tor ("TTV Radio") later became Radio MCOT on 25 March 1977 and became the nation's first 24-hour radio station.

Color television began in 1970 on TV3 and 1974 on TV9. Chong Kao (Channel 9) was renamed Modernine TV in 2002.


In 2005, the Ministry of Finance announced their plan to digitize free-to-air television broadcasts nationwide. Trial broadcasts were undertaken, involving 1,000 households in the Bangkok Metropolitan Area.

MCOT has prepared at least three new channels exclusively for digital television, besides the two initial channels, Modernine TV and Channel 3. Though the trials had been long over, the digital channels are (said to be) still active in test form.

In addition, MCOT would introduce regional television channels for each province in Thailand. Each of these regions will have its own dedicated television channel with localised content compared to national television making it about 80 television channels for a digitised MCOT as part of the state broadcaster's three-year restructuring plan. MCOT was expected to launch its digital terrestrial television services nationally in 2012. MCOT launched digital terrestrial television in 2013, with full service in 2014.

In March 2011, MCOT announced that it is also possible that MCOT may be planning to switch to DVB-T2 some time in the future.
