Comic strip in the context of "William Hogarth"

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.

Mickey Mouse is a cartoon character co-created in 1928 by Walt Disney and Ub Iwerks. The longtime icon and mascot of the Walt Disney Company, Mickey is an anthropomorphic mouse who typically wears red shorts, large shoes, and white gloves. He is often depicted with a cast of characters including his girlfriend Minnie Mouse, his pet dog Pluto, his best friends Donald Duck and Goofy, and his nemesis Pete.

Mickey was created as a replacement for a prior Disney character, Oswald the Lucky Rabbit. The character was originally to be named "Mortimer Mouse", until Disney's wife, Lillian, suggested "Mickey". Mickey first appeared in two 1928 shorts Plane Crazy and The Gallopin' Gaucho (which were not picked up for distribution) before his public debut in Steamboat Willie (1928). The character went on to appear in over 130 films, mostly shorts as well as features such as Fantasia (1940). Since 1930, Mickey has been featured extensively in comic strips (including the Mickey Mouse comic strip, which ran for 45 years) and comic books (such as Mickey Mouse). The character has also been featured in television series such as The Mickey Mouse Club (1955–1996).

A superhero or superheroine, is a character who typically possesses superpowers or abilities beyond those of ordinary people, is frequently costumed concealing their identity, and fits the role of the hero, typically using their powers to help the world become a better place, or dedicating themselves to protecting the public and fighting crime. Superhero fiction is the genre of fiction that is centered on such characters, especially, since the 1930s, in American comic books (and later in Hollywood films, film serials, television and video games), as well as in Japanese media (including kamishibai, tokusatsu, manga, anime and video games).

Superheroes come from a wide array of different backgrounds and origins. Most superheroes (for example, Superman and Spider-Man) usually possess non-human or superhuman biology, while others (such as Batman and Iron Man) derive their status from advanced technology they create and use, but some of them may use or possess objects that have superhuman, mystical, or alien powers (such as Green Lantern and He-Man), or study and practice magic to achieve their abilities (such as Doctor Fate and Doctor Strange). The Dictionary.com definition of "superhero" is "a figure, especially in a comic strip or cartoon, endowed with superhuman powers and usually portrayed as fighting evil or crime," and the Merriam-Webster dictionary gives the definition as "a fictional hero having extraordinary or superhuman powers; also: an exceptionally skillful or successful person." Terms such as masked crime fighters, costumed adventurers or masked vigilantes are sometimes used to refer to characters such as the Spirit, who may not be explicitly referred to as superheroes but nevertheless share similar traits.

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.

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.

A gag cartoon (also panel cartoon, single-panel cartoon, or gag panel) is most often a single-panel cartoon, usually including a caption beneath the drawing. In some cases, dialogue may appear in speech balloons, following the common convention of comic strips. A pantomime cartoon carries no caption (see also: pantomime comics).

As the name implies—"gag" being a show business term for a comedic idea—these cartoons are most often intended to provoke laughter. Popular magazines that have featured gag cartoons include Punch, The New Yorker and Playboy. Some publications, such as Humorama, have used cartoons as the main focus of the magazine, rather than articles and fiction.

Webcomics (also known as online comics or Internet comics) are comics published on the internet, such as on a website or a mobile app. While many webcomics are published exclusively online, others are also published in magazines, newspapers, or comic books.Webcomics can be compared to self-published print comics in that anyone with an Internet connection can publish their own webcomic. Readership levels vary widely; many are read only by the creator's immediate friends and family, while some of the most widely read have audiences of well over one million readers. Webcomics range from traditional comic strips and graphic novels to avant garde comics, and cover many genres, styles, and subjects. They sometimes take on the role of a comic blog. The term web cartoonist is sometimes used to refer to someone who creates webcomics.

A newspaper is a periodical publication containing written information about current events and is often typed in black ink with a white or gray background. Newspapers can cover a wide variety of fields such as politics, business, sports, art, science, and religions. They often include materials such as opinion columns, weather forecasts, reviews of local services, obituaries, birth notices, crosswords, sudoku puzzles, editorial cartoons, comic strips, and advice columns.

Most newspapers are businesses, and they pay their expenses with a mixture of subscription revenue, newsstand sales, and advertising revenue. The journalism organizations that publish newspapers are themselves often metonymically called newspapers. Newspapers have traditionally been published in print (usually on cheap, low-grade paper called newsprint). However, today most newspapers are also published on websites as online newspapers, and some have even abandoned their print versions entirely.
