Within each of the ages identified by Rhoades (2008b, pp. 227-229), he also outlines thirteen milestones:
• The comic book format as a magazine folded and stapled in a 6 5/8 X 10 3/16 format (although comics are actually a bit smaller today than comics printed until the mid-1970s).
• The formation of the two giants of the comic book industry, now named DC and Marvel, although the names went through various transformations over the years.
• The superhero subgenre of comics.
• The national attack on comics as a corrupting influence on children.
• The Marvel revolution of comics led by Stan Lee and Jack Kirby.
• Direct marketing of comics to comic-focused specialty bookstores.
• Comics shifting toward darker themes, topics, and characters, emerging as serious literature.
• Comics experiencing the rise of intellectual property and branching out into other markets—toys, movies, etc.
• Speculators creating a boom and bust in the comic market.
• Comic writers and artists achieving start status and demanding more power and rights.
• Marvel overcoming bankruptcy and the overall comics industry rebounding.
• Comics achieving success in films.
• Comics experiencing an expanded genre with graphic novels and manga.
"[C]omic books are history," Wright (2001) contends, and "[a]lthough [comics] are often grouped together with comic strips, the two mediums are not the same" (p. xiii).
