Television is by far the most popular medium in Thailand. More than 80% of Thais are estimated to rely on television as their primary source of news. The largest players in the Thai television industry are MCOT, a former state enterprise of which the government still owns 77%, and the Royal Thai Army, which retained ownership of numerous broadcast frequencies even after the end of military rule in Thailand. The only commercial station not subject to the control of MCOT or the army was iTV, once owned by Shin Corporation, a communications conglomerate controlled by Temasek Holdings of Singapore. On March 07. 2007 Thailands Government closed iTV, changed its name to TITV and hired MCOT to run the formerly independent station. On January 14 2008 the military junta changed the stations name and program again. It is known now as Thai PBS (or Thai Public Broadcasting Service) Thailand's public service broadcaster, Channel 11, is funded and operated by the Public Relations Department (PRD) of the Prime Minister's Office. During March 2008 the new (elected) government turned the state-owned Channel 11 into NBT (National Broadcasting Service of Thailand).

Thailand's six terrestrial TV stations are based in Bangkok and are relayed to all parts of the country through repeaters. Although Thailand has experimented with digital terrestrial television on a trial basis, the delays in establishing the NBC (National Broadcasting Commission) will likely slow the conversion from analogue to digital broadcasting technology.

Former iTV, once owned and operated by Shin Corporation under concession from the Prime Minister's Office. On March 07. 2007 the Prime Minister's Office took over management of iTV, changed its name to TITV and hired MCOT to run the formerly independent station. Since January 15 2008 the station is known as the Thai Public Broadcasting Service (Thai PBS).

Aside from terrestrial television, Thailand has several CATV, MMDS and Satellite television providers. The largest player in the market is the United Broadcasting Corporation (UBC). Outside Bangkok, hundreds of independent CATV providers offer services in the provinces. The PRD is technically in charge of regulating provincial cable operators. Thai TV (TTV) holds a concession from the PRD to operate an MMDS service in the Bangkok Metropolitan Area. TTV currently operates a free-to-air analogue MMDS service with three channels and an encrypted digital MMDS service that offers 16 channels. Nation Multimedia Group, a Thai media conglomerate, currently owns a 12% stake in TTV. Thus, content produced by the Nation Group's Nation Channel features prominently on TTV's programming line-up. ASTV, owned by news operation holding Manager Media Group, is a free-to-air satellite television network that offers eight channels via Ku band. Many provincial CATV providers also carry ASTV channels on their line-up.

Thailand has 204 AM stations, 334 FM stations and six shortwave broadcasters. As is the case with television, radio broadcasting is supposed to be regulated by the National Broadcasting Commission (NBC). However, because of delays in establishing the NBC, radio frequencies remain in the hands of a plethora of government agencies, including the military, state universities, the Posts and Telegraph Department, the Public Relations Department (PRD) and MCOT. These agencies operate several stations directly, while the remainder are leased out to private content providers. Community radio stations operated with low-power transmitters have proliferated in the last few years, offering listeners an alternative to the government-controlled stations. However, the government has recently shut down many community radio stations on the grounds that they operated stronger transmitters than permitted, interfering with existing frequencies.

MCOT Public Company Limited is a Thai media conglomerate. Its origins date back to the creation in 1955 of Thailand's first television broadcaster, The Thai Television Company Limited. In 1977, this company was reconstituted as a state enterprise, the Mass Communications Organization of Thailand. In August 2004, the Thai government corporatized the Mass Communications Organization of Thailand and renamed it MCOT Pcl. The company was partially privatized in an initial public offering later that same year, with the Thai Ministry of Finance retaining a 77 percent stake. Headquartered in Bangkok, MCOT operates a television station, Modernine TV (formerly Channel 9), and a nationwide network of at least 62 radio stations. The company also owns TV Channel 3, but contracts the management of that station out to a private operator, BEC World. In addition, MCOT operates the Thai News Agency (TNA) wire service.
