After the conclusion of the anime adaptation of Akira Toriyama’s hit series Dr. Slump, the 7:00 PM Wednesday time slot was taken over by his next work, Dragon Ball, on February 26, 1986. The series would go on for 153 episodes covering the first sixteen volumes of the manga, until its name was changed to Dragon Ball Z for 291 episodes covering the rest.
Along the way, in addition to covering all the manga material, anime-only story arcs known as “filler” were aired to “fill” up the time for Toriyama to get ahead on the manga. After Z reached its conclusion, Toei Animation continued with the anime-only series Dragon Ball GT, which lasted 64 episodes.
In 2009, a “refreshed” remastered, filler-free version of Dragon Ball Z began, taking a 9:00 AM Sunday time slot alongside One Piece, creating the Dream/Strong 9 Block on Fuji TV. This new series lasted for 98 episodes and received a new recording and musical composition by Kenji Yamamoto (although his score was plagiarised, prompting Toei to replace Kai’s music with the original series’ music by Shunsuke Kikuchi). Later in 2014 this new “refreshed” series titled Dragon Ball Kai returned with the Buu arc, having been cut short at the Cell Arc in 2011 due to lack of DVD sales, the music scandal, and the 2011 Tohoku Earthquake and Tsunami. Two versions were produced: one for the international market and the Japanese market; however the Majin Buu arc has not yet been announced for a North American release.
Dragon Ball Super, the first all new Dragon Ball series in 18 years, replaced Dragon Ball Kai on July 5, 2015, taking its 9:00 AM time slot on Sunday mornings on Fuji TV in Japan.
