One of world's largest and oldest international organizations, the International Telecommunication Union (ITU) was established in 1865 to manage the first international telegraph networks. Throughout it's history, the ITU has expanded to cover voice telephony, radio communications, communications satellites, and, most recently, the technological advances of a telecommunications-based information age. Primary standardization sectors cover Telecommunications (ITU-T) and Radiocommunications (ITU-R). Membership includes most of the world's countries and over 650 private members from telecommunication, broadcasting and information technology. Today's ITU works to ensure that the latest technological advances are integrated into the telecommunication networks of countries around the world
