in protests and unrest across the country, the location of the event was considered to be changed. Ukraine was considered an option since they came second in Eurovision Song Contest 2007. YLE were another option, as they hosted the previous year's competition in Helsinki, Finland. Greece's Ellinikí Radiofonía Tileórasi (ERT) also offered the EBU to host the contest in Athens, Greece again. It was later decided that the contest would stay in Belgrade, with the EBU giving support. RTS would gain a guarantee of safety and security from the government of Serbia for all visitors and participants of the contest. The delegations of Albania, Croatia and Israel had special security. In the end, the contest was held without any incidents. Visual design RTS ran a competition that led to the creation of the 2008 contest's branding, logo and the stage.

Each post card had a short story related to each country and its people. During each postcard a short letter was displayed. All were in the national language of the artist's country, with the exception of the Serbian postcard, which consisted of "Welcome to Belgrade" and "Welcome to Serbia" in various languages and the Belgian postcard which was written in the constructed language the Belgian group performed in. The postcards were brought to an end by a stamp with this year's Eurovision logo. According to RTS the stage represented native identities, history and modern themes, symbols and universally recognised messages. The confluence-themed stage also contained a large number of television and LCD display screens. The stage had settings for all new electronic possibilities including some movable parts of the stage. It was designed by Chicago-based David Cushing. The first semi-final was created around a city theme. The contest opened with a panorama of the city of Belgrade forming in the stage's background with two waves sliding down the stage to meet in the centre – at the confluence, the overall theme of the contest. The second semi-final was based around
