Origins of Break dancing

Here's a clip I stumble upon today. there's a lot of version of this on youtube, I guess this is as clear as it could get.
I think people should see this since it shows something about the history of dance.(not that everyone is into dancing,..but might be something new.)
I think its one of those video that says "what you see is what you get."

As of Today, The break dancing culture has been accepted worldwide and is often free of racial, stereotype boundaries and other negative aspects.
