The Nobel Peace Prize Concert (Norwegian and Swedish: Nobels fredspriskonsert) has been held annually since 1994 on 11 December, to honour the Nobel Peace Prize laureate. The award ceremony on 10 December takes place in Oslo City Hall, while the concert has been held at Oslo Spektrum, with the attendance of the laureate and other prominent guests. The Concert is broadcast to a global audience and reaches up to 350 million households in 100 countries. In 2015 a new distributor was announced and after 20 years at Oslo Spektrum, a change of concert venue was announced. The much larger Telenor Arena. The international entertainment giant IMG lost the job in obtaining sponsors and distribute it. Instead the concert will be produced by the Norwegian event agency Gyro in cooperation with the television production department to Norwegian Warner Bros, the former Eyeworks.The concert features performers from a wide range of musical genres, the exception being the year of 1995, when a classical concert was held instead. Several editions of the concert are recorded, with different lengths and content, for airing in several countries. The hosts give descriptions of the winner's work, an interview with the winner is shown, and the winner gives a speech during the concert. In 2018, the concert organizers announced that the show would be put on hiatus for 2018, hoping to hold a relaunched concert the following year. The official website stated, "The decision emerges from a wish to re-think the concert format and content but also reflects the challenging financial situation of the concert in recent years. Moreover, people’s media preferences have undergone radical change since the first concert in 1994. This is something the concert organizers and producers are keenly aware of as they move forward. We have struggled to maintain an appropriate level of financing and want to use the year ahead to develop a new format for the concert. Our ambition is to launch a renewed and better concert in 2019. [...] We plan to use this break to further develop the format and strengthen the financing beyond the continuing and generous support of our long term Norwegian sponsors. The firmer our financial base, the stronger our independence in choice of concert format and profile, say concert producers Odd Arvid Strømstad (Warner Bros. Norway) and Kristian Kirkvaag (Gyro)."
