Unusually, Hilversum 3 used to have more than one pop chart between 1974 and 1992. While its official Nationale Hitparade chart – supported by most public broadcasters – was hosted by the NOS, Veronica, once it received its legal status in May 1976, broadcast its own Top 40. Also, TROS introduced its own rival chart, TROS Top 50, on 1 June 1978 (it had previously broadcast the Europarade, a top 30 of the biggest hits in a number of European countries). For many years, you could listen to three separate charts on Hilversum 3: the TROS Top 50 on Thursdays, Dutch Top 40 on Fridays and Nationale Hitparade on Wednesdays.
