Speed Racer, also known as Mach GoGoGo (マッハGoGoGo, Mahha GōGōGō?), is a Japanese anime/manga franchise about automobile racing. Mach GoGoGo was originally serialized in print in Shueisha's 1958 Shōnen Book. It was released in tankōbon book form by Sun Wide Comics, and later re-released in Japan by Fusosha. Adapted into anime by Tatsunoko Productions, its 52 episodes aired on Fuji TV from April 1967 to March 1968. The anime was re-broadcast on Tokyo MX from July 1 to September 25, 2008. Selected chapters of the manga were released by NOW Comics in the 1990s under the title Speed Racer Classics. These were later released by Wildstorm Productions, a division of DC Comics, as Speed Racer: The Original Manga. In 2008, under its Americanized title, Speed Racer, Mach GoGoGo was republished in its entirety in the United States by Digital Manga Publishing and was released as a box set to commemorate the franchise's 40th anniversary, as well as serving as a tie-in with the 2008 film. The television series itself is an early example of anime becoming a successful franchise in the United States, spawning multiple spinoffs in both print and broadcast media.
