The format, created by Cowell, first launched as `Britain`s Got Talent` in 2007 and has subsequently been adapted for broadcast in 58 countries, producers of the show said.
The latest versions to air include those in Iceland and Brazil.
Alistair Richards, president of Guinness World Records, said in a statement that `Got Talent` was the new record-holder, pushing another British format `Strictly Come Dancing` into second place.
The BBC dancing show is currently occupying the UK headlines as the search for a replacement for long-time host legend Bruce Forsyth, aged 86, after he shocked the local media late last week by announcing his decision to step down after 10 years fronting the show.
`Got Talent` so far has versions across Europe, Asia Pacific, the Middle-East, Africa and the Americas.
