The advent of cyber fiction using digital media is a dominant sociological phenomenon because the wide spread use of computers and the rapid growth of internet users result in the popularization of writing in cyberspace. The activity of cyber communities highlights the issue of writing and technology, and the literary world cannot help but pay attention to writing in cyberspace. Korea is no exception. In Korea, Byung-Ik Kim first used the term “Cyber Fiction” and he considers cyber fiction equivalent to hyper fiction. Both types of fiction not only include the action of writing and reading novels or novellas in cyberspace, but develop the interaction between the writer and the reader through spontaneous communication in cyberspace. The writer sets up several stories in which readers can choose to read and the reader responds the main story by continuing the story. Thus, cyber fiction encourages the writer to experiment on writing and the reader to raise his or her voice through participation. The emergence of cyber fiction in Korea since the 1990s has largely affected Korean Literature in which the writers of ∙ The Challenge of Cyber Novel as a New Form of Literature | Park, Ja Hyon 187established fame secured their authority by excluding cyber fiction as legitimate literary medium. Scholars have studied cyber fiction as a suggestion of a new form of literature in Korea. Although cyber fiction is considered as marginalized in comparison to the form of printing novels, I believe that a new approach of cyber fiction,communication between the writer and reader and the probability of genre transformation, has contributed to the popularity of literature as well as the expansion of accessibility. Cyber novelists have challenged the conservative writing structure and linguistic scholars have concerned regarding the rapid transformation of language, especially among younger generation. The younger generation prefers to read cyber fiction, and the appearance of improper grammar and the transformation of signifiers affect the younger generation's use of daily language. For example, Kyŏn-u 74 (Kim Ho-sik)'s renowned cyber novel, My Sassy Girl (Yŏpkijŏgin Kŭnyŏ), well represents how he applies new language system to his writing and at the same time deconstructs the conventional writing system by creating a new type of relationship between the writer, and the reader, and the language system as well. The growth of cyber literature is considered to be a social phenomenon, and cyber literature should be regarded as a new form of literature. Though rapid, artificial linguistic transformation is regarded as a sociological concern, experimental and challengeable cyber fiction has greater possibility to promote the Korean literature in the era of advanced technology.
