Astro Boy's final regularly serialized series began 1980, to coincide with the release of the new animated television show. This new Astro Boy (1980-81) manga series began appearing in Second-Grader [小学二年生], a monthly magazine targeted at young students learning to read.
After all the regularly serialized manga series featuring Astro Boy came to a close, Astro was featured in a series of "one-shots" and other special editions.
After Mushi Productions' monthly Mighty Atom Club ceased publication altogether in 1966 and the primary serialization in Shonen [少年] finally concluded in 1968, The Astro Boy Chronicles (1967-69), being published in the Sankei Newspaper were the sole source for the regularly serialized adventures of the boy robot.
Published from August 1964 to November 1966, Astro Boy Fan Club members received a monthly publication known as Mighty Atom Club [鉄腕アトムクラブ] featuring exclusive "members only" Astro Boy stories and other Mushi-related content that weren't available to the general public.
