Reality: to most audiences the toilet (and the technology of sanitation in general) is just a punchline, and the show's producers know that. That's why we get so many toilets. We're getting what we pay for, and we vote with our eyeballs.

The proposed sealed toilet seat[0] is honestly a good idea, and seems a sensible implementation of the concept. I wish them luck. The TV segment felt oddly like a modern-day version of when John Snow first said "hey guys maybe don't drink cholera water, everyone." :-\
