Den Draayer kept presenting the show until April 2, 1971, when Felix Meurders replaced him.
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.
