The League of Nations and ITU decided not to create international broadcasting regulations as the technology was too "young" and changing too quickly.

The diverse and complex problems of a growing number of broadcasting stations in Europe required expert knowledge in law, finance, engineering, journalism, and musicology.

The experts argued that their efforts would improve the quality of broadcasting to such a degree that the medium would attract a wider radio audience.

In March 1946, the Soviet Union demanded dissolution of UIR and establishment of a new international broadcasting organization, where all the satellite states of the USSR would be represented with voting rights.

UIR was officially dissolved in 1950, and its remaining assets were transferred to a newly established European Broadcasting Union (EBU).
