Television Broadcasts Limited is a television broadcasting company based in Hong Kong SAR. The Company operates five free-to-air terrestrial television channels in Hong Kong, with TVB Jade as its main Cantonese language service, and TVB Pearl as its main English service. TVB is headquartered at TVB City at the Tseung Kwan O Industrial Estate. TVB commenced broadcasting on November 19, 1967. The Company was incorporated on July 26, 1965 and was co-founded by Sir Run Run Shaw, who was Chairman from 1980 to 2011, together with Sir Douglas Clague and Harold Lee Hsiao-wo of the Lee Hysan family. When TVB first began broadcasting it was commonly known and promoted as “Wireless Television” in Chinese to distinguish it from the then cable television broadcaster, Rediffusion Television, which later became ATV. It is still usually referred to with that name, although ATV later switched to “wireless” broadcasting as well.
