New school hip hop : New school rap

New school hip hop is a rarely-heard term referring to hip hop created later in the form's development, contrasted with old school hip hop. There is no exact division, with the dividing line being variously placed in the mid-1980s to the early 1990s. Run-D.M.C.'s Run-D.M.C.[?] (1984, 1984 in music) is one oft-cited boundary marker.
