The Eurovision Song Contest has transformed itself from a TV show experiment to the world's largest live music event.
160 million people are expected to watch this year's competition in Sweden, as 37 countries take part.
The acts participating will be hoping to become global superstars following the likes of ABBA, Celine Dion and Måneskin.
And outside of the competition many fans around have turned their love of Eurovision into a business: from side-hustles to songwriters. We hear their stories and learn about the economics of having a winning song, and discover the plans for the first ever Eurovision world tour.
