Britain's Got Talent has set a record after becoming the most popular reality show in the world. The talent show has set a Guinness World Record with 59 different versions being made in 58 different territories - including two in Belgium.
Among the most recent countries to make their own version are Kazakhstan, Brazil, Moldova and Iceland.
The show's creator and judge Simon Cowell said: "I am very proud that Got Talent is a home-grown British show. We owe its success to a group of very talented producers all over the world who have made this happen. And, of course, amazing talent."
Guinness World Records president Alistair Richards said: "We are delighted to confirm that Got Talent has broken the previous world record and is now the official Guinness World Record holder for the most successful reality television format, a landmark moment in television record-breaking history."

Simon Cowell and Cheryl Cole have spoken of their return to X Factor after their well-documented fall-out.
The pair fell out in 2011 after Cowell sacked Cole from the American version of the show after only three weeks as a judge.
She had only filmed one episode before being dropped by Cowell and the incident soured relations between the pair.
Speaking to Daybreak, Simon said: "I have done this a long time. You have fall-outs along the way. I held my hands up and said I made a mistake and I was sorry - and I was sorry. Then when I decided to come back, I also decided I had to have Cheryl back on the show with me."
Cheryl explained how she finally gave in to Simon's pleas to return to the ITV show: "There's only so much begging one can take and it's not nice to see a grown man cry, so I finally succumbed."
It is yet to be confirmed which other judges will be joining the pair on the show's panel.
