Manga (漫画 Manga) are comics or graphic novels created in Japan or by creators in the Japanese language, conforming to a style developed in Japan in the late 19th century. They have a long and complex pre-history in earlier Japanese art.
The term manga (kanji: 漫画; hiragana: まんが; katakana: マンガ; in Japan is a word used to refer to both comics and cartooning. “Manga” as a term used outside Japan refers to comics originally published in Japan.
In Japan, people of all ages read manga. The medium includes works in a broad range of genres: action, adventure, business and commerce, comedy, detective, drama, historical, horror, mystery, romance, science fiction and fantasy, erotica, sports and games, and suspense, among others. Many manga are translated into other languages. Since the 1950s, manga has steadily become a major part of the Japanese publishing industry. By 1995, the manga market in Japan was valued at ¥586.4 billion ($6–7 billion), with annual sales of 1.9 billion manga books and manga magazines in Japan (equivalent to 15 issues per person). Manga have also gained a significant worldwide audience. In 2008, in the U.S. and Canada, the manga market was valued at $175 million. Manga represent 38% of the French comics market, which is equivalent to approximately ten times that of the United States.
Manga stories are typically printed in black-and-white, although some full-colour manga exist. In Japan, manga are usually serialised in large manga magazines, often containing many stories, each presented in a single episode to be continued in the next issue. Collected chapters are usually republished in tankōbon volumes, frequently but not exclusively, paperback books. A manga artist (mangaka in Japanese) typically works with a few assistants in a small studio and is associated with a creative editor from a commercial publishing company. If a manga series is popular enough, it may be animated after or during its run. Sometimes manga are drawn centring on previously existing live-action or animated films.
