The standardization efforts of ITU started in 1865 with the formation of the International Telegraph Union (ITU). ITU became a Specialized agency of the United Nations in 1947. The International Telegraph and Telephone Consultative Committee (French: Comité Consultatif International Téléphonique et Télégraphique, CCITT) was created in 1956, and was renamed ITU-T in 1993.[1]
