Gold Key’s 1962 Space Family Robinson comicbook predated the Lost in Space TV show by three years and in spite of the similarities in theme and source (both are spacefaring revisions of the Swiss Family Robinson), neither were derivative of the other (at least according to the courts), so the pre-existing series settled for a licensing of the name “Lost in Space” from Irwin Allen to promote their smaller, yet still groundbreaking sci-fi comicbook.
The TV show lasted three interesting seasons, though, like its contemporary Star Trek it had its fair share of “cheesy” episodes toward the end. Also like Star Trek, Lost in Space found new life in syndication, the big screen and in comicbooks. The Space Family Robinson comicbook (initially unrelated) continued until the early 1980s (burgeoned by the resurrected success of Star Trek in Syndication). Much as the American Captain Marvel Comics series was continued after the fold of Fawcett comics in the form of Marvelman, the characters created for Space Family Robinson were continued in the UK’s Lady Penelope. Still, Lady Penelope didn’t last into the 1970s, while Space Family Robinson lasted until 1982.
