Congratulations: 50 Years of the Eurovision Song Contest was a television programme organised by the European Broadcasting Union (EBU) to commemorate the Eurovision Song Contest's fiftieth anniversary and to determine the Contest's most popular entrant of its fifty years. It took place at Forum, Copenhagen on 22 October 2005. The host broadcaster was Danmarks Radio (DR). Fourteen songs from the Contest's first half-century, chosen through an internet poll and by a jury, contested the event. Thirty-one EBU-member countries broadcast the concert (although the United Kingdom, Italy and France did not) and televoting and juries in these countries decided the winner. A total of 2.5 million votes were cast during the night.
