Overview
In comics, decompression is a stylistic storytelling choice characterized by a strong emphasis on visuals or character interaction, which, in turn, usually leads to slower-moving plots.
The style is often used with widescreen comics.
History
Decompression developed a strong presence in mainstream American comic books in the 1990s and 2000s. Traditionally, American comics first appeared as anthologies featuring multiple short stories per issue, usually with different characters, which continued for decades in the backup story pages. The done-in-one format prevailed for a long time eventually becoming seconded by open-ended multiple-subplots that characterized the 1970s and '80s in American comics.
Decompression is often claimed to be a result of the growing influence of manga on the international comics scene. Manga, traditionally less expensive per page than American comics due to higher circulation and black-and-white printing, extensively uses decompression as a storytelling style. This style of storytelling which was influenced by film storyboarding was first popularized in manga by cartoonist Osamu Tezuka with his 1947 manga Shin Takarajima (New Treasure Island). Tezuka's more "cinematic style" was so successful that it caught on with other cartoonists in Japan and eventually spread throughout the world with works such as Katsuhiro Otomo's epic Akira which was one of the first manga to become popular within the American comic book community.
