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 consisted of only six countries: the Netherlands, UK, France, Germany, Belgium and Spain). 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. Italy and Denmark were added in 1979 and during 1980, Austria and Switzerland were included. Ireland was added as the 11th country in October 1983.
In March 1984, Music & Media in Amsterdam started their own singles chart, "The Eurochart Hot 100", which they published as a Euro Tip sheet for the first two years. This chart was accumulated by taking the chart positions in each country combined with the national sales percentage of records in that particular country. In 1986-87, the official Eurochart also became a music TV show on Music Box with Dutch presenter Erik de Zwart. A syndicated radio show was also introduced on UK commercial radio. Hosted by Pat Sharp, it was broadcast on a number of stations including Radio Trent, BRMB and GWR FM.
The Eurochart quickly gained momentum, as it started to include more countries. From 1982 to 1986 the "Europarade", as published in Music Week and the Dutch magazine Hitkrant, was used. In January 1986, Music & Media became a Billboard publication. Since November 1986, the Music & Media's Eurochart Top 100 was used as basis when Billboard itself started publishing the European Hot 100 Singles chart.
