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. The series is serialized in Shogakukan's Weekly Shōnen Sunday since January 19, 1994, and has been collected in 76 tankōbon volumes as of June 2012. Due to legal considerations 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 by Yomiuri Telecasting Corporation and TMS Entertainment; the animated series has reached its twentieth season. The series has spawned two original video animation series, sixteen animated feature films, three live action dramas, a live action series, numerous video games, and many types of Case Closed-related merchandise. A two-hour television special titled Lupin the 3rd vs Detective Conan was aired on March 27, 2009, and featured a crossover with the series Lupin III.
Funimation Entertainment licensed the anime series for North American broadcast in 2003 under the name Case Closed with the characters 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. Viz Media later licensed the manga series for English-language publication in North America and used Funimation's renamed title and cast.
Compilation volumes of the manga have sold more than 120 million copies in Japan. In 2001, the manga was awarded 46th Shogakukan Manga Award in the shōnen category. The anime adaptation has been well received and ranked in the top twenty in Animage's polls between 1996 and 2001. In the Japanese TV anime ranking, Case Closed often ranked in the top six. Both manga and anime have had positive response from critics for its plot and cases.
