Short for International Telecommunication Union,
an intergovernmental organization through which public and private organizations develop telecommunications
. The ITU was founded in 1865 and became a United Nations agency in 1947. It is responsible for adopting international treaties, regulations and standards
governing telecommunications. The standardization functions were formerly performed by a group within the ITU called CCITT
, but after a 1992 reorganization the CCITT no longer exists as a separate entity.
