In the grand scheme of things, I don't think it matters all that much, and I just see it as something fun to talk about. It's TV. So when it is no longer fun, just ignore it. It looks like rating from "Pawn Stars" and "Storage Wars" are much higher, so doubt it will stay around that long. Most people willing to go to the effort of a huge/fancy tank will generally know better. A true beginner is not that likely to try to start with a tank remotely like that. Even most early grade school kids know that an octopus is not a fish. Sure, there are exceptions (ie morons), but I doubt they add up. Then again, looking at our politicians these days... Things like global warming, ocean acidification, overfishing, and so on have orders of magnitude more impact.
