Have you ever seen Dancing with the stars? It is very popular, it has been licensed to over 42 different territories
I may have watched some episodes in the past.
It used to be very popular, in 2006 and 2007 it was the most popular show in the world!
I had no idea, I bet that show is very popular with couples, maybe to learn to dance better. 
I liked it because the show had celebrities or professionals, I thought that was really cool, to see their routines and watch my favorite athletes
That definitely sounds like a good combination to put pro's on to keep the show interesting. 
Yup, and then the dancers are all scored by judges, who always had their own personalities as well, like American Idol!
