Nine Inch Nails were the most popular industrial group ever and were largely responsible for bringing the music to a mass audience. It isn't really accurate to call NIN a group; the only official member is singer/producer/multi-instrumentalist Trent Reznor, who always remained solely responsible for NIN's musical direction (he was, however, supported in concert by a regular backing band).
