It is an American program.
But, sadly, it is shown all over the world. We get it here in Germany on the free Astra satellite.
It is one of the major ways the other countries of the world form their opinion of the USA. That, and shows like Bad Trip, Blind Date, etc. All the wonderful exports of American culture we are so happy to share with everyone. I cringe every time I see this stuff on European television. It is sometimes funny - but do you want the world thinking we're all like that? Or contestants on Jerry Springer?
