The BRIT Billion Award is a special award given by the British Phonographic Industry (BPI) to artist who have achieved over one billion digital streams in the United Kingdom. An extension of the BPI's music certification system, the number of streams is verified using data calculated by the Official Charts Company and is the first time in the fifty-year history of the system that an artist's combined success over multiple projects has been recognized as a collective total. The one billion career streams include tracks where the artist is the primary performer, as well as tracks where they appear as a featured artist.
