I guess that all of us love to dance. As to me - I love it very much and use every moment off to dancing. So, probably the popularity of Dancing TV shows is so highly successful and atractive to people, there are a number of reasons why this show has become so popular over the years.
It's also important that most of the participants on the show become professional choreographers, actors, models and performers. There are many dancing TV shows and at the same time there are most favorite ones, such as So You Think You Can Dance, Dancing With The Stars and America's Best Dance Crew.
