The Ministry of Communications (MINCOM) was formed in April 1968 to oversee the planning and development of Singapore's transport and telecommunications sectors. Its main task was to develop and promote Singapore as a communications centre and to provide effective and efficient air, land and sea transport systems. The portfolios under its purview included the Marine Department, Meteorological Services Department, Registry of Vehicles, and postal and telecommunications services. Statutory boards under MINCOM included the Civil Aviation Authority of Singapore (CAAS), Mass Rapid Transit Corporation (MRTC), Port of Singapore Authority (PSA) and Telecommunications Authority of Singapore (TAS). On 2 Jan 1985, MINCOM was restructured to become the Ministry of Communications and Information when MINCOM absorbed the Information Service from the Ministry of Culture.
