Even with all the media attention and marketing blitz, there's still a few people that have no idea what Pokémon is. (Mainly adults that don't have kids.) Of course, they've heard of it, they're curious as to what it is. They might occasionally ask "What's the big deal about this 'Pokéman' stuff?", but they haven't found much of an interest in learning more about it. I can only imagine what they think Pokémon is...
Sorry if I've frightened anyone.
