Case Closed, which is also known as "Detective Conan" in Japan, is an anime television show that has been on the air for seventeen seasons, from 1996 to the present time. A manga version has also been available for even longer than that, ever since 1994. The show is about a teenage detective named Shiniji Kudo, who is poisoned by an evil group called "The Black Organization". The poison was supposed to kill him. However, the poison instead turned him into a small child. Shiniji adopts a new identity as "Conan Edogawa", and lives with his girlfriend, Ran Mouri, and her father, Detective Kogorou Mouri, under the pretense that his parents are away and unable to take care of him. As a child, Shiniji/Conan helps Kogorou solve murder cases, while trying to find the evil men who poisoned him, to steal the poison and create an antidote.
When "Detective Conan" first arrived in the United States, the owners of Conan the Barbarian asked the series to be known as "Case Closed" in English. Some of the character names had to be changed as well. Shiniji had his first name changed to Jimmy. Ran Mouri became Rachel Moore, while her father became Richard. However, Conan kept his Japanese name in English.
