History
The CCIR—Comité consultatif international pour la radio, Consultative Committee on International Radio or International Radio Consultative Committee—was founded in 1927.
In 1932 the CCIR and several other organizations (including the original
ITU, which had been founded as the International Telegraph Union in 1865), merged to form what would in 1934 become known as the International Telecommunication Union. In 1992, the CCIR became the ITU-R.
