^ I couldn't name you a single character from that show off the top of my head. Now I know it was very popular even though I personally didn't watch it, so maybe you are right. But I think to be considered "iconic," a character's name or likeness has to be recognizable even to people who have never seen them in a film or TV show.
For example, who hasn't at least heard of James Bond, Luke Skywalker, or Harry Potter? They are iconic without a doubt.
