My question stands, as per the thread title. Is Spock the first non-human or alien character to make regular appearances on television? Obviously, within teh past few decades, there have been many examples of non-human or alien characters in science fiction, sitcoms, dramas, or even anime (if that's a genre itself). I believe that Spock from Star Trek is a landmark character of this sort of category, and as far as I know, he is the first, correct me if I'm wrong. And also, here's a character that started off minor, quickly becoming a sort of "breakout character," and one of the best examples of such.
