It was only from the 1990s when the dance sport had begun to be practised in Korea. So the year 1978 when this IDSF event was held in the Western Germany was in fact quite early from the Korean point of view. Even USA a paradise of all kinds of dances didn't enjoy the dance sport earnestly. IOC, the Int'l Olympic Committee received an application from ICAD from 1980 that this so-called " Ballroom Dance" be included as an Olympic Sport and IOC reviwed it and concluded it should be called "Dance Sport" and from then on ICAD recommended its member nations to use the term "Dance Sport"...
