Comic book in the context of "Modern Age of Comic Books"

Comics are a medium used to express ideas with images, often combined with text or other visual information. It typically takes the form of a sequence of panels of images. Textual devices such as speech balloons, captions, and onomatopoeia can indicate dialogue, narration, sound effects, or other information. 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. Cartooning and other forms of illustration are the most common means of image-making in comics. Photo comics are a form that uses photographic images. Common forms include comic strips, editorial and gag cartoons, and comic books. Since the late 20th century, bound volumes such as graphic novels and comic albums have become increasingly common, along with webcomics.

The history of comics has followed different paths in different cultures. Scholars have posited a pre-history as far back as the Lascaux cave paintings. By the mid-20th century, comics flourished, particularly in the United States, western Europe (especially France and Belgium), and Japan. The history of European comics is often traced to Rodolphe Töpffer's cartoon strips of the 1830s, while Wilhelm Busch and his Max and Moritz also had a global impact from 1865 on, and became popular following the success in the 1930s of strips and books such as The Adventures of Tintin. American comics emerged as a mass medium in the early 20th century with the advent of newspaper comic strips; magazine-style comic books followed in the 1930s, and the superhero genre became prominent after Superman appeared in 1938. Histories of Japanese comics (manga) propose origins as early as the 12th century. Japanese comics are generally held separate from the evolution of Euro-American comics, and Western comic art probably originated in 17th-century Italy. Modern Japanese comic strips emerged in the early 20th century, and the output of comic magazines and books rapidly expanded in the post-World War II era (1945–) with the popularity of cartoonists such as Osamu Tezuka. Comics has had a lowbrow reputation for much of its history, but towards the end of the 20th century, it began to find greater acceptance with the public and academics.

A superpower is a special or extraordinary ability far greater than what is considered normal, possessed by those of superhuman status. Superpowers are typically displayed in science fiction and fantasy media such as comic books, TV shows, video games, and film as the key attribute of a superhero. The concept originated in American comics and pulp fiction of the 1930s and 1940s, and has gradually worked its way into other genres and media.

An action figure is a poseable character model figure made most commonly of plastic, and often based upon characters from a film, comic book, military, video game, television program, or sport; fictional or historical. These figures are usually marketed toward boys and adult collectors. The term was coined by Hasbro in 1964 to market G.I. Joe to boys (while competitors called similar offerings boy's dolls).

According to a 2005 study in Sweden, action figures which display traditional masculine traits primarily target boys. While most commonly marketed as a child's toy, the action figure has gained widespread acceptance as collector item for adults. In such a case, the item may be produced and designed on the assumption it will be bought solely for display as a collectible and not played with like a child's toy.

A panel is an individual frame, or single drawing, in the multiple-panel sequence of a comic strip or comic book, as well as a graphic novel. A panel consists of a single drawing depicting a frozen moment. When multiple panels are present, they are often, though not always, separated by a short amount of space called a gutter.

Newspaper daily strips typically consist of either four panels (Doonesbury, For Better or For Worse) or three panels (Garfield, Dilbert). These panels may all be of the same size, but many skilled cartoonists, such as Bill Watterson, can vary the size and number of panels in each daily strip. The horizontal newspaper strip can also employ only a single panel, as sometimes seen in Wiley Miller's Non Sequitur.

Speech balloons (also speech bubbles, dialogue balloons, or word balloons) are a graphic convention used most commonly in comic books, comics, and cartoons to allow words (and much less often, pictures) to be understood as representing a character's speech or thoughts. A formal distinction is often made between the balloon that indicates speech and the one that indicates thoughts; the balloon that conveys thoughts is often referred to as a thought bubble or conversation cloud.

A cartoonist is a visual artist who specializes in both drawing and writing cartoons (individual images) or comics (sequential images). Cartoonists differ from comics writers or comics illustrators/artists in that they produce both the literary and graphic components of the work as part of their practice.

Cartoonists may work in a variety of formats, including booklets, comic strips, comic books, editorial cartoons, graphic novels, manuals, gag cartoons, storyboards, posters, shirts, books, advertisements, greeting cards, magazines, newspapers, webcomics, and video game packaging.

An American comic book is a thin periodical literary work originating in the United States, commonly between 24 and 64 pages, containing comics. While the form originated in 1933, American comic books first gained popularity after the 1938 publication of Action Comics, which included the debut of the superhero Superman. This was followed by a superhero boom that lasted until the end of World War II. After the war, while superheroes were marginalized, the comic book industry rapidly expanded and genres such as horror, crime, science fiction and romance became popular. The 1950s saw a gradual decline, due to a shift away from print media in the wake of television and the impact of the Comics Code Authority. The late 1950s and the 1960s saw a superhero revival and superheroes remained the dominant character archetype throughout the late 20th century into the 21st century.

Some fans collect comic books, helping drive up their value. Some have sold for more than US$1 million. Comic shops cater to fans, selling comic books, plastic sleeves ("bags") and cardboard backing ("boards") to protect the comic books.

A disguise can be anything incognito which conceals one's identity or changes a person's physical appearance, including a wig, glasses, makeup, fake moustache, costume or other items. Camouflage is a type of disguise for people, animals and objects. Hats, glasses, changes in hair style or wigs, plastic surgery, and make-up are also used.

Disguises can be used by criminals, terrorists, secret agents and special forces operators seeking to avoid identification. A person working for an agency trying to get information might go "undercover" to get information without being recognised by the public; a celebrity may go "incognito" in order to avoid unwelcome press attention. Protests often feature people dressed in humorous costumes while political publicity stunts and pranks sometimes employ disguises and imposture. In comic books and films, disguises are often used by superheroes, and in science fiction they may be used by aliens. Dressing up in costumes is a Halloween tradition.
