Controversies of the Eurovision Song Contest
The Eurovision Song Contest is an international song competition organised annually since 1956 by the European Broadcasting Union (EBU) between its members who participate representing their countries. One of the stated aims of the contest is that the event is of a non-political nature, and participating broadcasters and performers are precluded from promoting or referring to anything of a political, commercial or similar nature during the contest.
