The results of countries finishing between 11th and 26th in the public vote are automatically added to the scoreboard, with only the results of the top ten countries being announced by the hosts.The new voting system is also used to determine the qualifiers from each semi-final, but as before the qualifiers are announced in a random order.
Portugal withdrew, largely due to their national broadcaster's insufficient promotion of their music-based media, while Romania had originally planned to participate, but was forced to withdraw due to repeated non-payment of debts by their national broadcaster to the European Broadcasting Union (EBU).
The contest was also the first to implement a voting system change since 1975: each country's professional jury points were announced largely as before, while the results of each national televote were combined and announced in reverse order.
A record-breaking 204 million viewers worldwide watched the contest, beating the 2015 viewing figures by over 5 million.
The contest took place in the Ericsson Globe in Stockholm, following Sweden's victory at the 2015 contest in Vienna with the song "Heroes", performed by Måns Zelmerlöw.
Friends Arena is the biggest football stadium and indoor venue in Sweden and the Nordic countries.
However, it was reportedly not part of Stockholm's bid.SVT proposed a change of start time of the contest from CEST to CEST on 9 September, arguing that such a change would help to promote family viewing of the contest, especially in eastern Europe when it would run late into the night.The EBU announced on 23 September that rather than using clips from their respective music videos, extended clips from the dress rehearsals of the six acts who qualified directly to the final (the "Big Five" and Sweden) would be shown as previews during the semi-final in which they were allocated to vote.As the new voting system gives equal weight to jury and televoting results, a national jury result cannot be used as backup result for the televoting or vice versa.Therefore, if a country cannot deliver a valid televoting/jury result, a substitute result is calculated by the jury/televoting result of a pre-selected group of countries approved by the contest's Reference Group.The core team for the contest was announced by SVT and the EBU on 26 October.
