Reliance jio-late, but the latest and later?
The licence for setting up telephone exchanges was given to a British company called 'Oriental Telephone Company' in 1881. This company constructed telephone exchanges in different cities of India like Calcutta (now Kolkata), Madras (currently Chennai) and Bombay (now Mumbai). Once India became independent from British rule in 1947, India's Ministry of Communication formed the Department of Post, Telephone and Telegraph by nationalizing different foreign telecom companies.1 It completely enjoyed its monopoly for a substantial time in providing telecom services in India. Private companies had to be satisfied only with the production of telecom equipment in India.2
