Sci-fi comics were a groundbreaking genre in the early 20th century. It is taken for granted today, but sci-fi comics were seen as a moral threat to America’s youth back then. EC Comics and other pioneering comic book publishers were forced to stop publishing horror in the mid-1950s.
The sci-fi genre didn’t die out, but there are many early-era sci-fi comics that are historically important today. Censorship authorities tried to wipe out sci-fi and horror comics forever in the 1950s, but did not succeed.
