History of manga
Modern manga, in the sense of narrative multi-panel cartoons made in Japan, originated from Western-style cartoons featured in late 19th century Japanese publications. The form of manga as speech-balloon based comics more specifically originated from translations of American comic strips in the 1920s; several early examples of such manga read left to right, with the longest running pre-1945 manga being the Japanese translation of the American comic strip Bringing Up Father.
