Nonetheless, mostly before the appearance of the Internet, when I was reading various technical journals, especially during the seventies and the eighties of the past century, e.g. magazines or journals of electronics or of computers, I was considering most ads as helpful, as they were making me aware of various things that I might have wanted to buy.
Unlike the ads that bother me today, those ads in magazines or journals intended for more competent buyers contained enough technical details and prices to make possible comparisons between products, and they were also easy to skip when not interested, instead of covering important content on a Web page and making efforts to provide a visual distraction that makes difficult to focus on the useful content of that Web page.
The Internet ads are completely unhelpful because they are never about something that I intend to buy in the near future. The most stupid thing is the fact that after I have searched for something to buy, I am bombarded for a long time with related ads, but that is exactly when with certainty I am no longer interested in that kind of ads, because I have already bought whatever I had been searching for.

And even the second is on shaky ground because by design it won’t tell you really where it stacks up.
I suppose you could argue that making you aware of sales/deals is “helpful” but that’s closer to what I’d classify most advertising as - zero-sum.
(Advertising of a different kind has a use, allowing companies to “sponsor” activities they like in a way the shareholders won’t revolt over. The more you consider companies to be feudal lordships the more it all starts to make sense.)
