the theme of water, which was enhanced by the look of the stage during the interval act where the water formed the main colours of the stage. The grand final was based on the theme of the confluence. Construction of the stage lasted several days and was carried out by various teams from across Europe. Pyrotechnics were heavily used for the entries from Armenia, Azerbaijan, Finland, Germany, Turkey, the Czech Republic, Bulgaria and Switzerland. The stage received positive feedback from the media and fans describing it as "one of the best looking stages in the history of the competition". 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 City Assembly of Belgrade on Monday 28 January 2008 at 13:00 CET and was conducted by the hosts of the contest Jovana Janković and Željko Joksimović. 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 grand 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 grand 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 grand final, and a tenth was determined by the back-up juries. Twenty-five songs competed in the grand final. Semi-final allocation On 24
