Fujiko Fujio
A similar trend in Japan also began appearing around the 1960s and 1970s, where independently published manga and novels, known as "dōjinshi", are frequently published by dōjin circles; many of these dōjinshi are based on existing manga, anime, and video game franchises. Manga authors like Shotaro Ishinomori and Fujiko Fujio formed dōjin groups such as Fujio's . At this time, dōjin groups were used by artists to make a professional debut. This changed in the coming decades with dōjin groups forming as school clubs and the like. This culminated in 1975 with the Comiket in Tokyo.
