The Rock Steady Crew was one of the most influencial breakdance crews out there at their time. The Rock Steady Crew was picked up by a record company and they made dope tracks and music videos. They spread breakdance around the world. If not for them the world of real hip-hop dance would still be limited to New York. The original founders were Jimmy D and Jojo, two early popularizers of breakdancing. Although breakdancing has since become a well-known subculture, in the late 1970s it was little known outside of New York, as such their early rivals were from the other boroughs of New York.
