text: The European Broadcasting Area is defined by the International Telecommunication Union as encompassing the geographical area between the boundary of ITU Region 1 in the west, the meridian 40° East of Greenwich in the east, and parallel 30° North in the south. Armenia, Azerbaijan, Georgia, and the parts of Iraq, Jordan, Syria, Turkey and Ukraine lying outside these limits, are also included in the European Broadcasting Area.
  Eligibility to participate in the contest is therefore not limited to countries in Europe, as several states geographically outside the boundaries of the continent or which span more than one continent are included in the Broadcasting Area. Countries from these groups have taken part in past editions, including countries in Western Asia such as Israel and Cyprus, countries which span Europe and Asia like Russia and Turkey, and North African countries such as Morocco. Australia became the first country to participate from outside the European Broadcasting Area in 2015, following an invitation by the contest's Reference Group.
  EBU members who wish to participate must fulfil conditions as laid down in the rules of the contest, a separate copy of which is drafted annually. A maximum of 44 countries can take part in any one contest. Broadcasters must have paid the EBU a participation fee in advance to the deadline specified in the rules for the year in which they wish to participate; this fee is different for each country based on its size and viewership.
  Fifty-two countries have participated at least once. These are listed here alongside the year in which they made their debut:
