Not only that, but ads pay for the otherwise free content. We used to have to trudge to the library, in the snow, uphill both ways, to pour over out of date books to try to find information. Or pay very high prices to have a librarian type searches into things like lexus nexus. Now we do this from home, for free. Not to mention stream film, download books, get college degrees, and so on.

Internet ads have transformed life as we know it, in a good way.

Advertising is a service designed to help corporations exploit psychology to induce people to buy their products.

What you are describing is more like a concierge. Hint: The person who pays is the person who's interests are being served.

Advertisements are more manipulative than informative. But the bigger point was that they are far less of a benefit to humanity than other things, yet they get far more resources allocated to them.
