History
The first broadcast in its current format 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 and since 5th. 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, including Veronica. 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 Olivier Bakker.

On television, the chart was used by TopPop from 1974 until 1978 and from 1982 until 1988. In the period 2000-2006 Top of the Pops NL used the public chart.

In January 2003, Music & Media reported that the although positions one to 50 of the Mega Top 100 would remain based purely on sales, that positions 51 to 100 would reflect a combination of sales and airplay data. However, since May 2004, Music Factory, MTV and NPO 3FM airplay data has been used in the composition of the full Mega Top 50 chart and 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 B2B Single Top 100. Since 2012 streaming data has been included in the composition of the Mega Top 50 chart.

The chart is compiled by SoundAware. Current composition is based on:
 * streaming data from Spotify
 * download data
 * radio airplay on Dutch radio stations: NPO Radio 1, NPO Radio 2, NPO 3FM, 100%NL, Q-music, Radio 538, Radio 10, Radio Veronica, Sky Radio and Slam FM.
