History

Domestic telecommunications facilities in Hong Kong became more advanced in 1925 when the Hong Kong Telephone Company Limited (HKTC) took over the interests of John Pender's China and Japan Telephone and Electric Company. The company's mandate included providing all the British colonies with local telephone services. Over the next six decades, Hong Kong Telephone's line capacity grew to more than 2.5 million, with the company serving approximately six million people.International Directory of Company Histories, Vol. 30. St. James Press, 2000.

Telecommunications became increasingly important following World War I, and in 1929 the British companies Marconi Wireless and Eastern Telegraph joined to establish Cable & Wireless. The company's strategy was to supply telephone and telegraph services in Britain's colonies, and it succeeded in securing an exclusive franchise to provide international communications services in Hong Kong.

By 1972, the company's biggest operation was its subsidiary in rapidly growing Hong Kong. Hong Kong Telephone, meanwhile, built a new headquarters in 1972. The company's growth was said to typify the colony's transition from an economy based on manufacturing to one dependent on service industries, which created a demand for telecommunications services. In 1975 Hong Kong Telephone's franchise for domestic service in the colony was extended for an additional 20 years, to expire just ahead of Hong Kong's reversion to China's control in 1997.
