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 17 European countries: Austria, Belgium (two charts separately for Flanders and Wallonia), Denmark, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Netherlands, Norway, Portugal, 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.[1] The final number one single on the chart was "Only Girl (in the World)" by Rihanna.
