This ad makes quite a fuss about their "Prolon" bristles. That's DuPont's marketing name for Nylon. Everybody had Nylon, but when DuPont calls it "prolon", it gets magically better. Using our powers of Living in the Future, we can tell that this was a failure. Have you heard anybody say the word "Prolon" in the last twenty years? Up yours, marketing bullshit!
Before there was Nylon, there was pig hair, or "natural bristle". Say it with me. "Bleah". I'll take Nylon, thanks. At least that comes out of a nice clean robot. Wanna see? Here's a How It's Made video all about toothbrush construction. You won't believe how fast the bristlebot moves. Who needs toothbrushes that fast? People with a hot date, that's who.
Here's the soldier trumpeting for your attention from today's ad. Maybe he'll be useful for something some day.
