Janet remains one of only seven albums in history to produce six top-ten hits on the US Billboard Hot 100 chart, including the number-one singles "That's the Way Love Goes" and "Again". The MTV-sponsored Janet World Tour supporting the album received critical acclaim for Jackson's elaborate stage performances, reinforcing her reputation as one of the preeminent artists of the MTV generation. 

Janet cemented her as an international icon and sex symbol, and is listed by the National Association of Recording Merchandisers and the Rock and Roll Hall of Fame as one of the 200 Definitive Albums of All Time. Academics argued the erotic imagery in her music videos have contributed to a higher degree of sexual freedom among women.
