In reply to Stephy..

I like Mariah but Janet and Whitney changed the game in other ways.

Janet put R&B on the map. New Jack Swing came from Control. RN1989 made R&B marketable to massive pop crowds which is way it became popular among large white crowds. She helped make videos one of the biggest promo tools for music. Her tours also made her rival that of Rock and Roll Legends.

Whitney helped put female vocalists back on the map when Pop and Rock was taking over. Tommy mirrored Mariah after Whitney.
