The term comics is used as a singular noun when it refers to the medium itself (e.g. "Comics is a visual art form."), but becomes plural when referring to works collectively (e.g. "Comics are popular reading material."). Though the term derives from the humorous (comic) work that predominated in early American newspaper comic strips, it has become standard for non-humorous works too. The alternate spelling comix – coined by the underground comix movement – is sometimes used to address these ambiguities. In English, it is common to refer to the comics of different cultures by the terms used in their original languages, such as manga for Japanese comics, or bandes dessinées (B.D.) for French-language comics.
There is no consensus among theorists and historians on a definition of comics; some emphasize the combination of images and text, some sequentiality or other image relations, and others historical aspects, such as mass reproduction or the use of recurring characters. Increasing cross-pollination of concepts from different comics cultures and eras has only made definition more difficult. (Full article...)
You know, I distrust people who 'read' comics ... you don't read a comic book. You look at a comic book.
