In 2003, the first 104 episodes were licensed by Funimation for distribution in North America, under the title Case Closedbecause of legal considerations.[2][46] The Case Closed anime has also been released in other languages such as French, German and Italian.[47][48][49] Case Closed debuted on Cartoon Network as part of their Adult Swim programming block on May 24, 2004;[50] no more than 50 episodes were licensed from Funimation due to low ratings.[51] The Canadian channel YTV picked up the Case Closed series and broadcast 22 episodes between April 7, 2006, and September 2, 2006, before taking it off the air.[52][53][54] Funimation made the series available with the launch of the Funimation Channel in November 2005; it was temporary available on Colours TV during its syndication with the Funimation Channel.[55][56] Funimation lost the rights to the series in 2018.[57]

A separate English adaptation of the series by Animax Asia premiered in the Philippines on January 18, 2006, under the name Detective Conan.[58][59] Because Animax were unable to obtain further TV broadcast rights, their version comprised only 52 episodes.[60] The series continued with reruns until August 7, 2006, when it was removed from the station.[61] The California based channel United Television Broadcasting (UTB) aired Detective Conan with English subtitles from 2011 until 2014, until episode 421.[62][63]

In January 2016, 52 episodes of the anime appeared on Netflix, initially under its original title Detective Conan before changing to its English moniker Case Closed. The episodes are listed as "season one", although in reality they are episodes #748 to #799. The episodes are only available in Japanese, but are subtitled. The availability is likely part of Netflix's efforts to expand its anime catalog.[70] As of 2018, the Detective Conan anime has been broadcast in 40 countries around the world.[71]
