The International Telecommunication Union (ITU) and the Universal Postal Union (UPU) are the two major international organisations that are involved in the regulation of international communications. The ITU deals with electronic communications including radio. The UPU deals with mail. As such, both organisations are of major importance in modern life. This volume provides an up-to-date analysis of their development from inception to the present as they have responded to technical and political change. It also makes suggestions for the future. The volume will be an invaluable resource for researchers and students, policy-makers, government officials and administrators, and legal staff in telecommunication and postal organisations.
