The contest is overseen by the Reference Group on behalf of the Participating Broadcasters. Each Participating Broadcaster is represented by a Head of Delegation.
Since 1957 - a few exceptions aside - the Eurovision Song Contest is organised by the national public broadcaster of the country that won the year before. For the Host Broadcaster, organising the contest is often an unprecedented but exciting challenge. Therefore, the Host Broadcaster often cooperates closely with the Host City. The Host Broadcaster's operations are being managed by its Executive Producer.
