The UK Singles Chart is a record chart compiled by the Official Charts Company (OCC) on behalf of the British record industry. As of 10 July 2015, the chart week runs from Friday to Thursday with the chart-date given as the following Thursday. Before this, the chart week ran from Sunday to Saturday, with the chart-date given as the following Saturday.
Since April 1973, the British Phonographic Industry has been classifying singles by the number of units shipped or by sales. The highest threshold is "Platinum record" and is currently awarded to singles that have shipped or sold over 600,000 units.[d] From July 2014 BPI certifications (along with the Official Singles Chart) include audio streaming at 100 streams equal to one unit; these are referred to as 'combined sales' or 'chart sales'. So, for example "All of Me" by John Legend was certified double platinum (1,200,000 combined sales) in October 2014 and became a million seller in January 2015.
