==Program== ===Doujin marketplace=== Comiket is focused primarily on the sale of doujin: non-commercial, self-published works. Approximately 35,000 circles (a term for groups or individuals who create doujin) participate in each edition of Comiket. Different circles exhibit on each day of Comiket; circles producing works on a common subject, such as a particular media franchise or manga genre, are typically grouped on the same day. The most common item sold at Comiket is doujinshi (self-published comics, novels or magazines), while a smaller number of circles sell doujin soft, analog (board/card/etc.) games, music, clothing, and other goods. These are often derivative fan works based on anime, video games, and other media, legal according to Japanese law (shinkokuzai). Since Comiket's inauguration, sample copies of all works sold at Comiket are collected and archived by ComiketPC, with over 2.1 million works having been archived.
