When I was three or four years old, I had one of those Remco toy Robots, with which I was madly in love. It was my one and only security toy, like Linus' blanket, that I took with me everywhere (even to day school, on a show-and-tell day, where I got upset that other kids were touching my toy robot. It wasn't pretty), and even slept with, even though it was not a soft, cuddly, bedtime toy. I eventually wore it out and broke it. It's the one toy from my childhood that I truly miss.
Whether we watched Lost in Space on CBS or Star Trek on NBC was an issue my parents and I fought over. For the most part they won, and I didn't get to see most of Lost in Space until my early teen years, when it was in syndication, relegated to Pat Robertson's television station, KXTX-TV 39, where several episodes were censored, i.e. not aired at all, due to fundamentalist Christian issues.
S1E19, 'Ghost in Space' - a seance is held
S1E25, 'The Space Croppers' - folk magic, a werewolf
S1E27, 'The Lost Civilization' - I've never known why. Maybe because Will had to kiss a princess.
S1E29, 'Follow the Leader' - possession by a spirit
S2E12, 'A Visit to Hades' - lighthearted depiction of someone mistaken for the Devil
S2E22, 'The Cave of the Wizards' - again, something like possession
S3E05, 'The Space Primevals' - depiction of evolutionary development, a machine serving as a god
S3E07, 'The Haunted Lighthouse' - J-5's invisible pet, the Zaybo, came across too much like a demon or witch's familiar
S3E21, 'Space Beauty' - the winner of a beauty pageant must be wed to a flaming suit of armor. Obviously the Devil...
Because Lost in Space always had teasers for next week, I quickly became aware that there were episodes I wasn't getting to see. The Christian Broadcasting Network left the teasers in place, but declined to show the episodes. Towards the end of the 1970s, CBN gradually relaxed a little, and I saw a couple of them. But most had to wait for the 1990s, when I bought the Columbia House VHS tapes. Episodes like 'The Lost Civilization' and 'Follow the Leader' were shockers; I'd never seen them before.
