Cyrus's early success as the face of Disney Channel's billion dollar franchise "Hannah Montana" played an important role as shaping the 2000s teen pop culture earning her the honorific nickname of "Teen Queen". Bickford stated "Hannah Montana" adopted a business model of combining celebrity acts with film, television, and popular music for a pre-adolescent audience. He called the series "genre-defining" and likened this model to 1990s teen pop artists such as Britney Spears and NSYNC, who were also marketed to children. Morgan Genevieve Blue of "Feminist Media Studies" stated the series' primary female characters, Miley and her alter ego Hannah, are positioned as post-feminist subjects in a way their representation is confined to notions of femininity and consumerism. "The Times" journalist Craig McLean named Cyrus the "world's biggest-ever teenage star".
