PRS for Music collects royalties from overseas on behalf of UK songwriters, composers, and music publishers and the body says the big hits from the two top performing British artists have helped push revenues.
In 2011 alone, UK songwriters and composers earned £187.7m. That was a 10% from 2010. The income earned overseas has also doubled over the last ten years.
Revenues are said to have increased within the last ten years primarily because of how popular British music is and because of improved licensing.
Harris and Adele are popular amongst American singers who have also asked them to write their songs.
Those include Rihanna and Nicki Minaj. Amongst the biggest consumers of British music are Brazil and China.
British artists also show interest in the country by performing in Brazil since it was awarded the 2014 FIFA World Cup of Football and the 2016 Olympic Games.
Royalties received from online sales by UK songwriters, composers and music publishers have increased within the last few years and should double by the year 2022.
