The European Hot 100 Singles was compiled by Billboard and Music & Media magazine from March 1984 until December 2010. The chart was based on national singles sales charts in 16 European countries: Austria, Belgium (separately for Flanders and Wallonia), Denmark, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Netherlands, Norway, Spain, Sweden, Switzerland, and the United Kingdom.
By the issue dated/week ending November 13, 2010[update], the European Hot 100 had accumulated 400 number one hits. The final chart was published on December 11, 2010, following the news of Billboard closing their London office and letting their UK-based staff go. The final number one single on the chart was "Only Girl (in the World)" by Rihanna. Currently, Nielsen SoundScan International-based Euro Digital Songs and Euro Digital Tracks are the only pan-European music charts that Billboard is publishing.
The first attempt at a Europe-wide chart was the Europarade, which was started in early 1976 by the Dutch TROS radio network. The chart initially consisted of only six countries: the Netherlands, UK, France, Germany, Belgium and Spain. In 1979 Italy and Denmark were added and during 1980, Austria and Switzerland were included. Ireland was added as the eleventh country in October 1983. The compilers collected the top 15 records from each country and then awarded corresponding points, depending which positions between 1 and 15 each record stood at. The "Europarade" was published in Music Week and the Dutch magazine Hitkrant.
