The European Broadcasting Union (EBU) is an independent, non-governmental, non-commercial body which promotes cooperation in international radio and television broadcasting. It acts as a broker through which broadcasters worldwide can exchange radio and television services and, in particular, news footage and complete programmes via Eurovision for television and Euroradio for radio. EBU has 117 members in 79 countries. The EBU was formed in 1950 and is the biggest union of broadcasters in the world. In addition to programme exchange, EBU is also concerned with organising special operations for broadcasting major events such as the Olympic Games and the World Football Cup, and negotiating rights for its members for such events. The EBU leads or contributes to the development of many new radio and TV systems: radia data system (RDS), digital audio broadcasting (DAB), digital video broadcasting (DVB), and high-definition TV (HDTV).
