In 1976, Mattel produced a "Superstar" variation of its Barbie doll. According to Sofia Johansson, the "canonical texts on stardom" include articles by Boorstin (1971), Alberoni (1972), and Dyer (1979) that examined the "representations of stars and on aspects of the Hollywood star system". Johansson notes that "more recent analyses within media and cultural studies (e.g. Gamson 1994; Marshall 1997; Giles 2000; Turner, Marshall and Bonner 2000; Rojek 2001; Turner 2004) have instead dealt with the idea of a pervasive, contemporary, 'celebrity culture'". In an analysis of "celebrity culture", Johansson states that "fame and its constituencies are conceived of as a broader social process, connected to widespread economic, political, technological, and cultural developments".
