The American translation was cancelled after 104 episodes due to it being in black and white and dealing with "depressing" issues, but in Japan, it went on for a full 193 episodes.
Ironically though, episode 32 - 56 in the Japanese line-up - entitled Moon Monsters, was made in full color as an experiment of color production. This episode was also intended to introduce another character, named No. 7, a character from another of Tezuka’s mangas who was to be the focus of a new series, the planned series never left the idea stage, despite being made in color, the episode was only ever aired in black and white.
