Online literature refers to the creation, distribution, and sale of literary works through the Internet platform, usually with the characteristics of interaction, multi-media, and virtual. The development of online literature could be traced back to the 1990s, when the Internet began to spread and people began to use the Internet to create and spread literature. With the continuous development of the internet, online literature gradually became a new form of literature. Although online literature had been developed for more than ten years, there was still no unified definition. Different platforms and media might have different definition and standards, so there was controversy over the definition of online literature. However, generally speaking, the characteristics of online literature were interaction, multi-media, and virtual. The works of online literature were usually published on the Internet platform, allowing readers to read, comment, and share them online. Online literature also used new technologies such as virtual reality to enhance the expressiveness and interaction of the works.
