Shōnen Club
Shōnen Club was a monthly boys' magazine begun by Kodansha in November 1914. The magazine initially featured articles, poetry and serialized novels, but it began to focus more on creating manga content by the 1930s. The first manga, Norakuro, was published in the magazine in 1931. The magazine's success lead to the sister-publication of Shōjo Club in 1923, which offered similar content, but catered for girls. Osamu Tezuka's Astro Boy first published in 1951 became an international phenomenon.Manga serialization
