Established on 7 November 1991 by INTOUCH, the Company was granted a 30-year Domestic Communication Satellite Operating Agreement by the Ministry of Transport and Communications (currently transferred to the Ministry of Information and Communication Technology-MICT).
His Majesty the King Bhumibol Adulyadej officially names the satellites of this project "Thaicom", as a symbol of the linkage between Thailand and modern communications technology.
The Company became a listed company on the Stock Exchange of Thailand on 18 January 1994, and is officially traded under the symbol THCOM. Since its establishment, the Company has expanded its business activities to include Internet and telephone services, and DTV satellite television dish sales. As of 31 December 2012, INTOUCH, which is the Company's major shareholder, holds 41.14% of the Company’s shares. Thaicom has launched 6 satellites, Thaicoms 1, 2 and 3 (all de-orbited), Thaicom 4, (IPSTAR), Thaicom 5 and Thaicom 6. The company has also built high-quality satellite service facilities besides its main earth control station. This teleport and DTH center has been ISO9001:2000 certified since 2002.
Innovations have brought global attention to Thaicom. The company was the first in the region to offer Ku-band, Digital Direct-to-Home broadcasting as well as the world’s first operator to employ MPEG-2 DVB compression since 1994. Thaicom also developed and launched the world’s first Internet Protocal (IP) satellite, IPSTAR. This broadband satellite fully supports telecommunications via Internet Protocol.
