I found this fascinating: the story of the growth of the bottled water industry, and the advertising that made it happen.
This is an interesting case. I don't think advertising can make people buy something for which they don't feel a real need or which isn't so rewarding in some way that people come to see it as a need, and which doesn't to some degree provide what it purports to provide. At least not over a period of years--little bubbles of basically nonsensical enthusiasm--fads--can probably be generated with little more than clever marketing. But bottled water seems to be somewhere between those. I suspect that most people who habitually drink bottled water have a vague idea that it's healthier than tap water, but as the article says for most people this is not true. So apparently it is satisfying a need that is either based on misinformation, uncorrected for decades now, or is just some purely emotional but nevertheless persistent phenomenon.
