A lot of Americans will tell you that their country is solely responsible for kickboxing. But... While they had a big part in the development of it. It is originally derived from a combination of boxing, an English/European sport/method of fighting, and muay thai or thai boxing, another combat sport, but invented by the Thai people.
Kicboxing blends the kicking techniques (and knees and elbows if you're taught for street fighting too) of Muay Thai, with the more conventional punching and footwork techniques of western boxing.
All in all. It is the most popular "hybrid" as some people would call it, in the world. It is lots of fun, a good way to get some decent fitness, and a good skill to have.

Kickboxing is a Full contact sport in which two guys will kick each other's asses using all of their bodies as opposed to just their hands.

Martial arts commonly used in Kickboxing are: Karate, Muay Thai, Choy Li fut (or Choy lee fut or choy lay fut), or Sanda (or Sanshou).
