Richard Dyer developed the star persona theory which argues that audiences are influenced by their perceptions of stars based on constructed images rather than the actual person. A key difference between pop performers and pop stars is that pop stars develop broader cultural impacts and identities beyond their music over time. Stars are constructed images made of various media rather than real people, as evidenced by reality shows like The X Factor that style contestants to match audience and record label expectations. K-pop group Twice is given a cute, girlish persona through their performances and videos, though their choreographer altered a dance to be more mature but it did not fit their constructed image.
