The appearance of music videos changed entertainment: they often glorified urban neighborhoods. The music video for "Planet Rock" showcased the subculture of hip hop musicians, graffiti artists, and b-boys/b-girls. Many hip hop-related films were released between 1982 and 1985, among them "Wild Style", "Beat Street", "Krush Groove", "Breakin", and the documentary "Style Wars". These films expanded the appeal of hip hop beyond the boundaries of New York. By 1984, youth worldwide were embracing the hip hop culture. The hip hop artwork and "slang" of U.S. urban communities quickly found its way to Europe, as the culture's global appeal took root. The four traditional dances of hip hop are rocking, b-boying/b-girling, locking and popping, all of which trace their origins to the late 1960s or early 1970s.
