That the idea of Dickens and the adjective ‘Dickensian’ continue to have a cultural resonance which extends beyond the book‐buying public almost two centuries after Dickens's birth is testimony to his sense of himself as a mass cultural artist. This book contends that Dickens's popularity is unique, different even from that of Shakespeare because, writing in ‘the first age of mass culture’, Dickens was instinctively aware of the changed context of art, or of the need for popular art to find its place in an age of mechanical reproduction. The book describes the ways in which he envisioned and engineered his cultural pervasiveness, the media that enabled it, and the posthumous processes — technological, commercial, ideological, and emotional — that have perpetuated it. The first part examines Dickens's cultural vision and practice — his model of authorship, his journalism, his public readings, his relationship with America and the machine — and the second part explores Dickens's screen and ‘heritage’ afterlives, as well as the Dickens visitor attraction, ‘Dickens World’. Dickens's one‐time presence on the ten‐pound note symbolizes the book's guiding interest in the relationship between the commercial, cultural, and political aspects of Dickens's populist vision and legacy. The book argues that the aspects of Dickens's art that have underscored critical ambivalence about Dickens — his relationship with money, mechanical reproduction, and the mass market in particular — have ultimately ensured both his iconic cultural status and his centrality to the academic canon.
