Digital Narratology is the study of narratology in the new media forms that have arisen with the advent of computer technology. This area of study looks at hypertext novels such as Victory Garden by Stuart Moulthrop, network fiction (online) such as 253 (book) by Geoff Ryman Text based interactive fiction The Hitchhiker's Guide to the Galaxy (computer game) publish by Infocom, MUD's, blogs, video games and alternate reality games. A large part of the area involves comparing the new forms to old and seeing how things such as the ability to link pages in a non-sequential manner changes the narrative and that a different readers can have wildly different experience of the same piece of work.
