Anyone?
This whole “advertising is useful” thing sounds like the spherical cow of marketing to me. It might make sense in abstract but it doesn’t reflect reality.
Also: sales. I have bought things in sales that I would not have bought otherwise (because its value to me is higher than the sale price but lower than the normal price) where I was only aware of the sales from ads.
But that doesn’t mean it’s a major benefit of advertising. There are plenty of other ways to discover products, and most advertising is done by established brands to people who already know about them. How much advertising do Apple, Coca-Cola, Toyota, etc. do? How many people are unaware that their products exist?
But it only works where you have specialized focus and experienced/informed consumers that are able to separate the sizzle from the steak. For example, doctors and other medical professionals are generally well qualified to assess the claims of pharmaceutical advertising, consumers are not - even though I am comfortable reading the fine print in such ads and even reading papers about clinical trials, I still rate my evaluative ability as mediocre compared to a professional.
Mass market advertising for general consumers is generally cancer, imho.
I hate the step after raking where you have to use the rake and one hand to carry the leaves to the bin. There was an ad for "rake hands" where you just hold a small hand-formed rake in each hand and scoop them both.
Twenty bucks, vastly improved yardwork experience, and I would have literally never thought to look for something like that.
