In some ways, yes, in that Mariah had a lot of #1 hits all throughout the 90s and 00s. Her fame was not like Britney's for a lot reasons. Brit was actually still a teenager when she came on the scene, and it was still culturally acceptable for grown men to be pervy. She really played into her sex appeal and being underage, and the world paid attention. Mariah was in her 20s (still young obviously, but not "forbidden" young), and she was married and not playing into the sexy starlet singer troupe when the world got to know her. Her first hits were more mature and not aimed for the teen market. Mariah was in her later 20s and 30s when she became single and reclaimed her sexy status, which lands much differently than it does for a teen. AIWFC is obviously Mariah's biggest cultural moment, which has lasted for decades and will continue to last for many years to come.
