As winners of the 2009 event, with the song Fairytale sung by Alexander Rybak, Norwegian broadcaster NRK had the task of organising the 2010 contest. They selected the Fornebu Arena in Bærum just outside the nation's capital city Oslo as the venue.
39 countries registered to participate in the contest, including Georgia, which had missed the 2009 edition, though several countries withdrew that had been in the 2009 contest, mainly due to the budgetary constraints, namely Andorra, Czech Republic, Hungary and Montenegro.
On the 7th of February a draw was determined as to which countries were to participate in which Semi-Final, and as to which Semi-Final the five automatically countries would vote in.
The draw to determine the precise running order was made on the 23rd of March, with four countries drawn in the Semi-Finals able to choose their start position from within their respective half of the draw. In Semi-Final One this was Serbia and Belarus who could choose and in Semi-Final Two it was Switzerland and Bulgaria. In the Final, just one of the automatic finalists could choose their position, and it was Germany who chose position 22.
On the 10th of March it was revealed that there would be three presenters in total, with Nadia Hasnaoui presenting the voting sequence, and Erik Solbakken and Haddy Jatou N’jie introducing the artists and providing coverage from the Green Room.
Rehearsals started on Sunday 16 May with each country having a first rehearsal of 40 minutes on stage. Later on in the week the second rehearsals would be of 30 minutes duration.
The Semi-Finals took place on Tuesday the 25th May and Thursday the 27th May, with 17 countries participating in each Semi-Final, with ten countries from each Semi-Final qualifying for the Grand Final to join the Big Four countries (Germany, Spain, France and the United Kingdom) and host nation Norway. You can find full details of Semi-Final One and Semi-Final Two on our history pages, along with a full breakdown of the voting.

The Spanish entrant Daniel Diges had to perform his entry again at the conclusion of the 25 songs thanks to the unwanted stage invasion by the prankster known as Jimmy Jump during his first performance. See the first performance below;

Viewers in each country could vote by telephone or SMS, and professional juries in all 39 participating countries also judged the songs. The country's 10 favourites weree awarded 12, 10, then 8 through 1 points based on votes. Juries and televoters each had a 50% say in the outcome of every country's points.
Denmark made an impressive start in the voting by securing the 12 points from the first two juries of the evening, but it wasn't to be their victory in 2010. There was also a good early showing from Belgium, Turkey and Greece, but it was Germany who took the lead in the seventh round of voting and never lost the lead after that.

About the winner
Lena Meyer-Landrut had already created history in the German record charts, when all three of her songs from the German national final. debuted in the top five singles, including Satellite at the number one position.
Satellite topped the charts in half a dozen countries, and reached the top ten of several more countries all across Europe. It also became the first Eurovision winner to top the European Hot 100 singles, which combines the charts of 15 European countries. Outside of Europe it also reached the top 40 in Australia. Her first album My Cassette Player also topped the German and Austrian album charts.
Lena became the first singer since Corry Brokken defended her title in 1958, to try and win back to back victories in the contest. However her entry in 2011 Taken By A Stranger could only achieve a respectable tenth place when the contest was staged in Düsseldorf.
She has continued her career by performing in concerts across Germany, and has won several awards including two MTV Europe Music Awards for Best German Act and Best European Act.
