Internet and multimedia platforms are changing the way adolescents read and interact with literature, and in turn changing the way many writers for adolescents approach their readers and their work. Three authors of popular young-adult literature, Lois Lowry, J.K. Rowling, and John Green, demonstrate a range of approaches and responses to new communities of readership and “fandom.” The communities built around successful adolescent reader franchises have begun to engage in both online interaction and real-world activities such as charitable fundraising and fan publishing; this phenomenon may change the nature of adolescent literature and has even broader possible implications.
