The Russians had just launched Sputnik I, inaugurating the Space Race and renewing interest in science fiction. The first two television series designed to tap into the national excitement featured adult themes in a science fiction setting. As it turned out, the public wasn't that interested after all and both shows stopped production after only one season. The next step, using continuing characters to explore mature themes, would have to wait a few more years for Roddenberry to create Star Trek.
