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 1.9billion manga books and manga magazines in Japan (equivalent to 15issues 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. In France, the manga market was valued at about €460 million ($569million) in 2005. In Europe and the Middle East, the market was valued at $250 million in 2012.
Manga stories are typically printed in black-and-white, although some full-color manga exist (e.g., Colorful). In Japan, manga are usually serialized 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 centering on previously existing live-action or animated films.
The word "manga" comes from the Japanese word 漫画, composed of the two kanji 漫 (man) meaning "whimsical or impromptu" and 画 (ga) meaning "pictures". The same term is the root of the Korean word for comics(manhwa) and the Chinese word(manhua).
The word first came into common usage in the late 18th century with the publication of such works as Santō Kyōden's picturebook Shiji no yukikai (1798), and in the early 19th century with such works as Aikawa Minwa's Manga hyakujo (1814) and the celebrated Hokusai Manga books (1814–1834) containing assorted drawings from the sketchbooks of the famous ukiyo-e artist Hokusai.Rakuten Kitazawa (1876–1955) first used the word "manga" in the modern sense.
In Japanese, "manga" refers to all kinds of cartooning, comics, and animation. Among English speakers, "manga" has the stricter meaning of "Japanese comics", in parallel to the usage of "anime" in and outside Japan. The term "ani-manga" is used to describe comics produced from animation cels.
