It works very well for the HUGE players who sell it, Google, Meta, Amazon and not many more.

It can help a small advertiser get a small number of customers to try out their offering.

It does not and will not create brands. If you disagree, please tell me about brands created by “Internet advertising” in the current century.

That is sort of the inferred conclusion of the podcast, it is a bit of a racket by the big players.

I wrote a very short ebook on the subject some 10 years ago, 15 Questions About Online Advertising.

It should be available for free on Apple Books, Google Books, Kobo etc, or for 0.99 on Amazon.
