When was Tae Kwon Do first considered a sport?

The ancient roots and influences on modern Taekwondo were more cultural and philosophical than precise techniques, and began as an aspect of military defense among the early inhabitants and the three kingdoms developing from 57 BC to the 1st Century AD throughout the peninsula (modern day Korea) and some of the mainland area known as Choseon. Early Korean warriors incorporated hand fighting similar to that taught in China, and Wrestling, and created their own unique native skills of kicking that eventually became the impetus which inspired the foot techniques as a primary weapon of Taekwondo.
