Doujinshi.

"Upon the appearance of Web 2.0 sites like YouTube or DeviantART (and especially their explicitly Japanese counterparts NicoNico Dōga and Pixiv) one might think that Comic Market as a physical and costly event would suffer from losing its monopoly on being the center of Japanese fan art. But once again Comiket was the beneficiary of a new fan praxis: attendance reached new heights in 2007 (well over 500,000 people), a year without any outstandingly popular property to attract new visitors. It seems that dōjinshi circles are not switching entirely to the Internet but rather are using it as an informational and marketing platform for themselves and their creations, spreading the knowledge of and fascination with Comic Market to new spheres. The best example of this phenomenon is the already-mentioned Tōhō Project, which became popular mostly through Web 2.0 outlets."
