Format
At a press conference in Helsinki in May 2007, Svante Stockselius, executive supervisor of the Contest for the EBU, announced that the competition's format may be expanded to two semi-finals in 2008 or 2009. On 28 September 2007 it was announced that the EBU had approved the plan of hosting two semi-finals in 2008.
Based on research conducted by the EBU's tele-voting partner Digame, the semi-finalists were sorted into the two heats through the drawing of lots, which was seeded to keep countries that have a significant history of voting for each other apart. Each broadcaster had to broadcast the semi-final in which they took part, with the broadcasting of the other semi-final being optional. The draw for the semi-final allocation occurred in the Belgrade City Hall on Monday 28 January 2008 at 13:00 CET and was conducted by dancers from the National Dance Ensemble KOLO. First, two envelopes with 'Semi-Final 1' and 'Semi-Final 2' were drawn. Then, three countries from each pot were chosen randomly to take part in the first semi-final and the other three in the second one. The country left in Pot 5 took part in the first envelope that is drawn. While, the country left in Pot 6 in the second one.
The automatic finalist countries chose whether they would broadcast both semi-finals or just one, but viewers from these countries could only vote in one. From the draw conducted, it was decided which of the five finalist countries would broadcast and have voting rights in either of the events. The semi-finals were webcast live through Eurovision.tv. The top nine songs from the televoting qualified for the final, and a tenth was determined by the back-up juries. Twenty-five songs competed in the final.
