The first broadcast was on Friday May 23, 1969. The show was presented by Joost den Draayer. Desmond Dekker & The Aces were the chart toppers at that time with "The Israelites". From December 4, 1970, the chart was compiled by the NOS. Den Draayer kept presenting the show until April 2, 1971 when Felix Meurders replaced him. From 1978 until 2005 the year end charts were based on sales.
The radio-broadcast remained on Radio 3/3FM and since 5 December 1985 the chart has been broadcast by the TROS. Only during the period of 1993-1995, the show was broadcast by other broadcasting organizations. From 2007 until November 2014 the chart was hosted by Bart Arens. His place was taken by Paul Rabbering. Barend van Deelen was the presenter from 2015 until 2017. The current presenter is Kevin van Arnhem.
Since May 2004, Music Factory and Radio 3FM airplay data have also been used in the composition of the chart. Exactly one year later, digital downloads were also included. The chart that made use of single sales figures only kept on existing though, under the name of Single Top 100. Since 2012 streaming data has been included in the composition of the chart.
The chart is compiled by SoundAware. Current composition is based on 
- streamingdata from Spotify
- radio airplay on Dutch radiostations NPO Radio 2, NPO 3FM, 100%NL, Q-music, Radio 538, Sky Radio and Slam FM.
