In Japan people of all ages read manga. The genre includes a broad range of subjects: action-adventure, romance, sports and games, historical drama, comedy, science fiction and fantasy, mystery, horror, sexuality, and business/commerce, among others. Since the 1950s, manga have steadily become a major part of the Japanese publishing industry, representing a 406 billion yen market in Japan in 2007 (approximately $3.6 billion). Manga have also become increasingly popular worldwide. In 2008, the U.S. and Canadian manga market was $175 million. Manga are typically printed in black-and-white, although some full-color manga exist (e.g. Colorful). In Japan, manga are usually serialized in telephone book-size manga magazines, often containing many stories, each presented in a single episode to be continued in the next issue. If the series is successful, collected chapters may be republished in paperback books called tankōbon. 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 even during its run, although sometimes manga are drawn centering on previously existing live-action or animated films.
