TDM Ou Mun, formerly known as TDM Chinese, owned by TDM - Teledifusão de Macau, S. A., is the first broadcasting channel in Macau. It is free-to-air, and in the Cantonese language. It is mainly focused on local news and informative programs such as "TDM News", "Macau Forum" and "Financial Magazine" etc. Also, it includes local living programs such as "Our people, our life" etc.
It was the only television channel in Macau until 1990, when the Portuguese-language programming spun-off to its own channel in 1990.[1] TDM planned to create the channel in late 1987, with initial test broadcasts scheduled for January 1988. By broadcasting in Cantonese, it would also lure potential viewers in Hong Kong. The service would also attract the Hong Kong advertising market in line with its ban on tobacco advertising scheduled for 1990, but would cause concern from the Hong Kong government because viewers would be attracted to "dangerous" advertisements.[2]
From 15 August 2023, TDM Ou Mun will also available to cable systems within the Pearl River Delta region of China, with a formal launch date of 1 October.[3] [4]
