 Although comics has some origins in 18th century Japan and 1830s Europe, comic books were first popularized in the United States during the 1930s.
 The first modern comic book, "Famous Funnies", was released in the United States in 1933 and was a reprinting of earlier newspaper humor comic strips, which had established many of the story-telling devices used in comics.
 The term "comic book" derives from American comic books once being a compilation of comic strips of a humorous tone; however, this practice was replaced by featuring stories of all genres, usually not humorous in tone.

John Stanley (March 22, 1914 – November 11, 1993) was an American cartoonist and comic book writer, best known for writing Little Lulu comic book stories from 1945 to 1959.
 While mostly known for scripting, Stanley also drew many of his stories, including the earliest issues of "Little Lulu" and its "Tubby" spinoff series.
 His specialty was humorous stories, both with licensed characters and those of his own creation.
 His writing style has been described as employing "colorful, S. J. Perelman-ish language and a decidedly bizarre, macabre wit (reminiscent of writer Roald Dahl)", with storylines that "were cohesive and tightly constructed, with nary a loose thread in the plot".
 He has been compared to Carl Barks, and cartoonist Fred Hembeck has dubbed him "the most consistently funny cartoonist to work in the comic book medium".
 Captain Marvel co-creator C. C. Beck remarked, "The only comic books I ever read and enjoyed were "Little Lulu" and "Donald Duck"".
Centaur Publications (also known as Centaur Comics) (1938–1942) was one of the earliest American comic book publishers.

 From 1960 to 1969, Snapper Carr appeared as a supporting character to the Justice League of America, a superhero team.
 The character occasionally appeared in comics featuring the Justice League from 1969 to 1989, when the "Invasion!
" limited-series comic book gave him superpowers.
 He was associated with a new superhero team, The Blasters, in various comics until 1993, when he lost his powers and became a main character in the "Hourman" comic book.
 After the cancellation of "Hourman" in April 2001, he became a main character in the "Young Justice" comic book beginning in December 2001.
 "Young Justice" was cancelled in May 2003, and he became associated with the governmental organization Checkmate, a role revealed when the character played a small but important role in the 2007-2008 limited series comic book "52 Aftermath: The Four Horsemen".
 The character made major appearances in "Final Crisis: Resist" in December 2008 and "Justice League of America 80-Page Giant" in November 2009.
