Case Closed, known as Meitantei Conan (名探偵コナン?, lit. Great Detective Conan, officially translated as Detective Conan) in Japan, is a Japanese detective manga series written and illustrated by Gosho Aoyama. It has been serialized in Weekly Shōnen Sunday since 1994, and has been collected in 70 tankōbon volumes as of November 2010. To avoid copyright issues with the name Detective Conan, the English language release was renamed Case Closed. The story follows the adventures of Jimmy Kudo, a prodigious young detective who was inadvertently transformed into a child after being poisoned.
Since its publication, Case Closed has spawned a substantial media franchise. The manga has been adapted into an ongoing animated television series produced by TMS Entertainment and Yomiuri Telecasting Corporation. The series has spawned fourteen original video animations, fourteen animated feature films, numerous video games, and many types of Case Closed-related merchandise.
Viz Media licensed the manga series under the name for English-language publication in North America and released 36 volumes as of October 12, 2010. Funimation Entertainment licensed the anime series for North American broadcast. Both English adaptations went under the name Case Closed and the characters in the series were given Americanized names. The anime premiered on Cartoon Network as part of their Adult Swim programming block and was discontinued due to low ratings. The first six films were released on Region 1 DVD in North America.
Compilation volumes of the manga have sold over 120 million copies in Japan. The anime adaptation has been well received, ranking in the top twenty in Animage's polls between 1996 until 2001, when it dropped below the top twenty. In the Japanese TV anime ranking, Case Closed often ranked in the top six.
