Silver Age of Comic BooksThe Silver Age of Comic Books was a period of artistic advancement and widespread commercial success in mainstream American comic books, predominantly those featuring the superhero archetype. Following the Golden Age of Comic Books and an interregnum in the early to mid-1950s, the Silver Age is considered to cover the period from 1956 to 1970, and was succeeded by the Bronze Age. The popularity and circulation of comic books about superheroes had declined following World War II, and comic books about horror, crime and romance took larger shares of the market.
