Sometimes tap water is bad. I lived in a house with extremely hard water, and it was basically undrinkable. Of course, I was generally buying water in gallon or 2.2 gallon containers at the time. When I buy bottled water today, I want an unflavored drink that is healthy. In my view, what I am actually paying for is not water. I am paying for a disposable bottle, convenience, and usually cold. That's why I pay extra for the sport bottles with the better top. There was probably latent demand for this, but people didn't know they actually wanted it. In general, at least in the US, because of the abundance created over the last 30 years through the production of cheap manufactured goods and innumerable process improvements, people are more willing to pay for things they never would have before. And also, I am glad they succeeded in selling deodorant. It is definitely a quality of life improvement, as I notice when I visit places where deodorant usage is not prevalent. I generally don't view marketing as adversarial like many people though. If something exists that will improve my life, I want to know about it.
