For more than 65 years, the UK singles chart has provided a rundown of the records we listen to.
Now that is about to change. From July 6, the chart will include online views of music videos as the rules are adapted to reflect the going importance of YouTube and other video sites as a means of discovering to new music.
It was YouTube that helped decimate the blockbuster music video by slashing production budgets and undermining the commercial models of music video channels, such as MTV and VH1, but in an ironic twist, data from the streaming service will now be used, alongside new video data from Apple Music and Spotify, by the the Official Charts Company (OCC), and merged into the Top 100.
