By chance I watched that Pamela Anderson video of Dancing with the stars on YT. I wonder why this dancing is called argentine tango. I have never done ballroom dances, but what I saw in this video I would rather call ballroom tango than argentine tango. Can someone here tell me something about the classification, rating, and the jury? How and where did this style evolve? Is it popular in the US? Who promotes it, and in which kind of dancing schools can you learn to dance this way?
