The Eurovision Song Contest 2007 was the 52nd edition of the Eurovision Song Contest. It was won by first-time appearance as an independent country Serbia and was held at the Hartwall Areena in Helsinki, Finland from 10 May to 12 May. The host broadcaster was YLE. Finland earned the right to host the event after heavy metal band Lordi's victory at the Eurovision Song Contest 2006. It was the first time the Contest had been held in Finland. A budget of €13 million was presented for arranging the contest. Other bids to host the contest came from Espoo, Turku and Tampere. The hosts were Finnish television personality Jaana Pelkonen and Finnish musician, stage performer and actor Mikko Leppilampi. Krisse Salminen acted as guest host in the green room, and reported from the crowds at the Senate Square.
A record number of 42 countries participated. The European Broadcasting Union (EBU) put aside its limit of 40 countries, which would have meant excluding some countries using a ranking order scheme.
After Lordi scored the first ever Eurovision victory with a hard rock song in 2006, several countries sent rock songs to the Contest rather than the soft pop and schlager styles more closely associated with Eurovision. This trend continued at the 2008 and 2009 Contests.
