A comic book or comicbook, also called comic paper or comic magazine (often shortened to simply comic or comics) is a magazine made up of comics, narrative artwork in the form of separate panels that represent individual scenes, often accompanied by dialog (usually in word balloons, emblematic of the comic book art form) as well as including brief descriptive prose. The first comic book appeared in the United States in 1933, reprinting the earlier newspaper comic strips, which established many of the story-telling devices used in comics. The term "comic book" arose because the first comic books reprinted humor comic strips. Despite their name, comic books are not necessarily humorous in tone; modern comic books tell stories in a variety of genres.

Since the introduction of the comic book format in 1933 with the publication of Famous Funnies, the United States has produced the most titles, with only the British comic and Japanese manga as close competitors in terms of quantity of titles, though manga has many more followers and dwarfs American comics in readership.^{[citation needed]}

Gwendolyn "Gwen" Stacy appears as a supporting character in Marvel Comics' Spider-Man series. Created by writer Stan Lee and artist Steve Ditko, she first appeared in The Amazing Spider-Man #31 (December 1965).

A blonde college student, Gwen was originally the first love of Peter Parker (Spider-Man) before the introduction of Mary Jane Watson. The Green Goblin (Norman Osborn) killed Gwen in The Amazing Spider-Man #121 (June 1973). Both the decision to kill Gwen and the method in which Marvel implemented it remain controversial among fans, but the death became a pivotal point in both Spider-Man’s history and in American comic books in general. Many point to Gwen's death as the end of the so-called Silver Age of comics. Spider-Man writers and fans disagree about who is the character’s "one true love;" Gwen or his subsequent love-interest Mary Jane. The character was ranked 89th in Comics Buyer's Guide's "100 Sexiest Women in Comics" list.

In the 2007 feature film Spider-Man 3, Gwen is portrayed by Bryce Dallas Howard. In the upcoming reboot The Amazing Spider-Man she will be played by Emma Stone.
