The voting system that became the standard for all subsequent Eurovisions and started this year, was created as an evolution of the system used between 1971 and 1973. In those years, there were two jury members per country, one older than 25 and the other younger than 25, with at least ten years between their ages, who gave from 1 to 5 votes to each and every song excluding their own. In 1974 the tried to use the same system but by phone and with juries of 10 members. It became unpractical because the voting was excruciatingly long, so they had to switch back to the old system used up until 1970.
In 1975, the juries were composed of 11 members, with a wide variety of ages. Each of these jury members gave from 1 to 5 votes to each and every song excluding their own. Then a chairman collected all these votes and counted them, and the song with the highest amount of votes would receive 12 points, the second would get 10 points, the third 8, the fourth 7 and so on until the tenth which would get 1 point (in case of ties allocating the points, the juries voted again to break the ties and if still there was any tie in this second round of voting, the vote of the youngest member would be final). These points were the ones which would read aloud by the spokesperson in the live broadcast, the rest of the process would happen internally in each country under the supervision of a notary to ensure the legality of the voting. With this conversion, a quicker voting process was ensured.
