The activities of the International Broadcasting Union (IBU‑UIR) ceased with the outbreak of World War II: its observation and technical center in Brussels fell under Nazi control and served the Wehrmacht, including as a listening station for Allied radio communications. After the war, the IBU was considered discredited due to its collaboration with the Nazi regime and did not enjoy the trust of European countries, especially the USSR, which insisted on its dissolution. Meanwhile, the United Kingdom, which suspended relations with the IBU in 1941, was considering ways to revive the IBU in a new format, vacillating between temporary membership in it and an emphasis on the priority of redistributing waves between major countries before creating some kind of new broadcasting association. On 14 June 1946, the BBC notified the committee for the re-establishment of the union of its refusal to join the IBU. Two weeks later, the UK actually found itself on the sidelines of international cooperation. Without British participation, 26 members founded the OIR on 28 June 1946. The next day, at the General Assembly of the
International Broadcasting Union (IBU), an attempt was made to dissolve this body, but the motion failed to obtain the required majority. However, 18 of the 28 existing members left the IBU and become co-founders of the new OIR. In 1946, the newly created OIR installed itself in the IBU building in
Brussels. Technical activity was taken up again under the authority of two directors, one delegated by the
Soviet Union and the other by
France. However, the political situation gradually degraded into the
Cold War and this created an uneasy situation of distrust within the staff of the Technical Centre. In 1950, some members (mostly western European) left the organization to form the new
European Broadcasting Union (EBU), among them
Belgium,
Egypt, France,
Italy,
Lebanon,
Luxembourg,
Monaco,
Morocco,
Netherlands,
Tunisia and
Yugoslavia. Staff members from Belgium and other Western countries, some of whom had already been active before the war, stayed on in Brussels and the centre became the technical centre of the new
EBU. Unlike the EBU, the OIRT was not limited to European and Mediterranean countries and operated as a global organization. Members of the organization included countries aligned with the Eastern bloc, such as
Cuba,
Vietnam, the
People's Republic of China and
North Korea (although the latter's membership was temporarily inactive after their break with the USSR), as well as the allies of the USSR that were temporarily led by communist parties, such as
Nicaragua and the
Democratic Republic of Afghanistan, and the African and Middle Eastern states having been temporarily associated or supported by the
socialist camp. Since 1957, OIRT has established cooperation with the European Broadcasting Union at the level of technical committees, and since 1965, cooperation has begun between the programming committees of these organizations. Since 1960, the OIRT and the EBU have been actively cooperating on the following issues: expanding the exchange of artistic programs between Intervision and Eurovision, as well as solving legal and financial difficulties; expanding the exchange of relevant programs; technical work of exchange networks, especially qualitative improvement of image and sound channels for broadcasting; distribution of rights to broadcast major international sports events, as well as advertising issues within these broadcasts, the cost of licenses for sports programs. On November 18, 1971, nine OIRT members signed an agreement on the creation of the Intersputnik system. In 1986, OIRT developed the concept of the international channel Interprogramm. == Intervision ==
