The first two anime series were directly based off the Dragon Ball manga, which took much longer to produce than the anime did. This often resulted in "filler" episodes, one of the most obvious of which is when Frieza tries to destroy Planet Namek with a five-minute timer, yet the battle lasted well over five episodes, much less five minutes. Since Dragon Ball GT was not based on the manga, no filler episodes were required. As a result, four entire sagas (the Black Star Dragon Ball Saga, the Baby Saga, the Super 17 Saga, and the Shadow Dragon Saga) were completed in only 64 episodes. The music for Dragon Ball GT was composed and written by Akihito Tokunaga, replacing Shunsuke Kikuchi.
Dragon Ball GT began on Fuji TV at 7:30 p.m. on Wednesday, February 7, 1996, exactly one week after the final episode of Dragon Ball Z. It ran for 64 episodes, the last of which aired on November 4, 1997. It has also been aired across Japan by the anime television network, Animax, where it is currently being regularly broadcast. Unlike the Dragon Ball and Dragon Ball Z series, the creator Akira Toriyama had only minor involvement in the show's early stages, setting forth the initial premise of the series, as well as creating designs for most of the villains and main characters, including newcomer Giru. Early episodes are much more comedic in tone, reminiscent of early Dragon Ball. The later episodes, however, are action-packed and feature the same sort of dramatic tone that existed in Dragon Ball Z. Originally intended to span 40 episodes (ending after the Baby Saga), the series continued for another 24 episodes, ending after two years on the air seemingly due to lower-than-expected ratings. There are no subsequent Dragon Ball anime or manga (rumors of new series have existed since the end of Dragon Ball GT in 1997, but are untrue), except the Dragon Ball Kai series, which is simply a condensed remake of Dragon Ball Z rather than being an entirely new plotline.
There are two companion books to the series, called the Dragon Ball GT Perfect Files, released in May 1997 and December 1997 by Shueisha's Jump Comics Selection imprint. They include series information, illustration galleries, behind-the-scenes information, and more. They were out of print for many years, but were re-released in April 2006 and this edition is still in print.
On June 15, 2005, Toei Animation (in conjunction with distributor Pony Canyon) released the entire series (including the Gokū Jr. TV special) in an extremely limited-edition DVD boxed set (called "Dragon Box GT"), along with a Dragon Radar remote control and an exclusive booklet. While the set features remastered audio and video, there are no subtitles, English or otherwise. It's also unavailable to general public due to its scarce numbers and its huge cost.
