A comic book, also called comic magazine or (in the United Kingdom and Ireland) simply comic, is a publication that consists of comics art in the form of sequential juxtaposed panels that represent individual scenes. Panels are often accompanied by descriptive prose and written narrative, usually, dialogue contained in word balloons emblematic of the comics art form. Although comics has some origins in 18th century Japan, comic books were first popularized in the United States and the United Kingdom during the 1930s. The first modern comic book, Famous Funnies, was released in the US in 1933 and was a reprinting of earlier newspaper humor comic strips, which had established many of the story-telling devices used in comics. The term comic book derives from American comic books once being a compilation of comic strips of a humorous tone; however, this practice was replaced by featuring stories of all genres, usually not humorous in tone.
The largest comic book market is Japan. 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 (tankōbon volumes and manga magazines) in Japan, equivalent to 15 issues per person. The comic book market in the United States and Canada was valued at $1.09 billion in 2016. As of 2017, the largest comic book publisher in the United States is manga distributor Viz Media, followed by DC Comics and Marvel Comics. Another major comic book market is France, where Franco-Belgian comics and Japanese manga each represent 40% of the market, followed by American comics at 10% market share. Wikipedia
