Origins of manga

Although the origins of manga could be traced back to as early as the 12th century, the first example of manga-style art was probably Osamu Tezuka's manga-comic Astro Boy, which was started in 1952. Astro Boy was later made into the first anime.

It should be noted that manga-comics -- Japanese comics -- actually existed long before the production of Astro Boy in 1952, but Astro Boy represented the beginning of the evolution of the manga art style. Hokusai Manga was the first example of a manga-comic.
