Breaking was born when street corner DJ's (in legend it is DJ Kool Herc who was first) would take the breakdown sections (or "breaks") of dance records and string them together or loop them without any elements of the song per se. This provided a raw rhythmic base for improvising and further mixing, and it allowed dancers to display their skills during the break. Breakdancing has a variety of influences, there is no tradition in breakdancing, dancers picked elements from other dances and sports including but not limited to gymnastics, Capoeira, lindy hop, disco, etc…
Popular speculations of the early 1980s suggest that breakdancing, in its organized fashion seen today, began as a method for rival gangs of the ghetto to mediate and settle territorial disputes. In a turn-based showcase of dance routines, the winning side was determined by the dancer(s) who could outperform the other by displaying a set of more complicated and innovative moves.
It later was through the highly energetic performances of the late funk legend James Brown and the rapid growth of dance teams, like the Rock Steady Crew of New York City, that the competitive ritual of gang warfare evolved into a pop-culture phenomenon receiving massive media attention. Parties, disco clubs, talent shows, and other public events became typical locations for breakdancers, including gang members for whom dancing served as a positive diversion from the threats of city life.
Though its intense popularity eventually faded in the mid-1980s, in the following decades breakdancing became an accepted dance style portrayed in commercials, movies, and the media. Instruction in breakdancing techniques is even available at dance studios where hip-hop dancing is taught. Some large annual breakdancing competitions of the 2000s include the Battle of the Year or the Red Bull BC One.
