Tio i Topp was a radio show that first broadcast in 1961 and was the first official Swedish music chart. Initially broadcast through Sveriges Radio P2, it switched to Sveriges Radio P3 in 1964. Sveriges Radio started the chart in response to criticism from the public, who felt that there wasn't enough material oriented towards a young audience on their radio stations, but also as a way to combat music charts from pirate radio stations Radio Nord and Radio Syd, who had started compiling charts during the late 1950s. The idea behind the show was coined by Carl-Eiwar Carlsson and Klas Burling, who both had history of working in record shops and as such knew what records most teenagers and young adults were buying and consuming and thus wanted to lead a radio show based on this.
