The European Broadcasting Union (EBU; ) is an alliance of public service media entities, established on the 12 February 1950. As of 2015, the organisation comprises seventy-three active members in fifty-six countries, and thirty-four associate members from a further twenty countries. Most EU states are part of this organisation and therefore EBU has been subject to supranational legislation and regulation. It also hosted debates between candidates for the European Commission presidency for the 2014 parliamentary elections but is unrelated to the institution itself. It is best known for producing the Eurovision Song Contest.
