US singer Ariana Grande has made British chart history by becoming the first number one single based on sales and streaming.
It is the first time songs played on streaming services like Spotify, Deezer, Napster, O2 Tracks, Xbox Music and Sony's Music Unlimited have counted towards the chart rankings alongside physical and digital sales, the Official Charts Company said.
The 21-year-old singer/songwriter's hit Problem, featuring Iggy Azalea, now tops the charts with a combined "chart sales" figure of 113,000.
With 100 streams counting as a single purchase, the number of plays from streaming sites made up 6% of her success in topping the charts as there were 712,000 audio streams, the Official Charts Company said. Grande also pulled in 106,000 sales.
Of her debut number one, Grande said: "I'm so happy. Yay."
