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.
Adele achieved her first number-one single in February 2011 with "Someone Like You", which became the year's biggest seller; having spent five weeks at the peak and sold over 1 million copies. The singer later broke records with her comeback single "Hello", which reached the number one spot in November 2015, staying there for three weeks.
Canadian singer Carly Rae Jepsen achieved her first number-one single in 2012 with the international hit "Call Me Maybe", which spent four consecutive weeks at the summit.
Gary Barlow achieved his fourteenth number-one single with "Sing"—whilst also becoming the first artist in 2012 to have the UK number-one single and album in the same week.
Jess Glynne made chart history in 2015, scoring five number-ones in just 18 months; the fastest for a British female artist in the UK.
Canadian singer Justin Bieber achieved his first three number one singles in 2015. The first, "What Do You Mean?", was number one for five weeks, followed later in the year by "Sorry", which topped the chart for two weeks before being knocked off the top spot by Bieber's third single "Love Yourself", which has held the top spot for six weeks, tying him for the most number of weeks spent at number one by an artist this decade.
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.
