Eurovision 2010 had three presenters, Erik Solbakken, Haddy N'jie and Nadia Hasnaoui - the latter had previously hosted the Junior Eurovision Song Contest.
For the first time, the phone lines for voting were opened as soon as the first song had begun performing, remaining open until 15 minutes after the last song had been performed. A graphic showing the phone number appeared on screen part of the way during each song.
The postcards began with golden glowing balls forming the shape of the competing country, followed by clips of a flashmob gathering in that country, reflecting the contest's theme of 'Share the Moment'. Uniquely, these images were displayed over the heads of the live crowd in the contest's venue, the Telenor Arena in Oslo, and were interspersed with live scenes of the performer making their way to the stage.
Due to a stage invasion during its first performance, the Spanish entry was given a chance to perform again once all the other songs had been shown.
With Graham Norton commentating on the contest for the second time for BBC1 viewers, the semi-finals on BBC3 were commentated on by Paddy O'Connell and Sarah Cawood, both for the final time. Radio 1 DJ and Eurovision fan Scott Mills announced the UK's points during the voting sequence.
Eurovision returned to Germany in 2011 for the first time since 1983, hosted from the Esprit Arena in Dusseldorf. One of the presenters was Stefan Raab, who had already had a long association with the contest, having been involved with the German entries on a number of occasions since 1998, including as performer in 2000. He was joined by Anke Engelke and Judith Rakers to co-host this year's contest.
The postcards showed scenes of people in Germany, with each clip beginning with a diorama, or toy-like, effect. The postcards ended with the slogan, 'Feel Your Heartbeat', spoken or written in the competing country's native language. The performances then began with the contest's heart logo pulsating on the LED backdrop to the stage accompanied by the sound of a beating heart. This sound effect could also be heard throughout the voting sequence.
Phone lines for voting were, for the second and final time, open for the whole duration that the songs were being performed. The UK's votes were announced by The One Show's Alex Jones, while Scott Mills took over semi-final commentary duties with BBC3, this year being joined by fellow Radio 1 DJ Sara Cox.
This year Jon Ola Sand took over as the contest's Executive Supervisor, remaining in the role ever since.
With the slogan 'Light Your Fire', the 2012 contest was hosted at the newly-built Baku Crystal Hall in Azerbaijan. Eldar Gasimov, who had sung as part of the previous year's winning duo Ell and Nikki, presented the show alongside Leyla Aliyeva and Nargiz Birk-Petersen.
The postcards showed scenes of the host country under titles such as 'Land of Art', 'Land of Water' and 'Land of Carpets'.
The phone lines reverted to only being open after all the songs had been opened. Scott Mills announced the UK's points, having once again commentated on the semi-finals with Sara Cox.
The 2013 contest was the first to be introduced with the new Eurovision logo. This opening animation has been seen at every show since.
For the first time since 1995, this year's show had just one main presenter - Petra Mede. Eric Saade, who had represented Sweden at the contest in 2011, hosted from the green room. The show came from the Malmo Arena, and began with a 'Parade of Nations', culminating in all the acts gathering on stage. With this procedure taking up extra time, the show was the longest yet, running for a full three-and-a-half hours.
The show's theme was 'We Are One', using a butterfly as its motif, and each postcard began with a CGI butterfly with its wings decorated in the colours of the competing nation's flag. The postcards depicted the contestants in their home countries.
Scott Mills was this year joined by Ana Matronic of the Scissor Sisters for BBC3's semi-final commentary, with Scott again announcing the UK's votes.
