Doujinshi are also comics, but they are a kind of copycat comic. The creation of doujinshi is governed by a creators' ethic stating that a work is not doujinshi if it is just a copy; the artist must make a contribution to the art he copies by transforming it either subtly or significantly... These copycat comics exhibit significant market penetration as well. More than 33,000 "circles" of creators from across Japan produce doujinshi. More than 450,000 Japanese come together twice a year, in the largest public gathering in the country, to exchange and sell them. This market exists in parallel to the mainstream commercial manga market. In some ways, it obviously competes with that market, but there is no sustained effort by those who control the commercial manga market to shut the doujinshi market down. It flourishes, despite the competition and despite the law.""
