Advertising enables innovation-producing firms to drive awareness of their services in a cost effective manner, and for less informed consumers to understand what is available on the market. Your typical physician might not be fully caught up on what is the state of the art in arthritis treatments, but advertising enables this to happen.

Advertising as a source of consumer information is a market for lemons in and of itself. Everyone is free to claim innovation and deliver trash, and internet brands are a dime a dozen. Even just keeping out overt fraud/scams or propaganda campaigns is apparently a losing battle for platforms.

Reviewers/Influencers/interest-publications are often just a half-step above banner ads, but at least has more incentives than just "loudly capture attention" and "publish anything that pays the algorithmic sticker price".

> in a cost effective manner

Facebook is currently showing me these ads:

Lady's earrings (see my name), Pixel 10 (I'm theoretically an iPhone developer), cat food (I don't own any pet let alone a cat), special offers from a supermarket I would have been shopping at anyway even if they had not told me about the offers, a sponsored government message because apparently the Bundesministerium für Gesundheit don't have a better method of contacting German residents than by buying ads from a US social network (I have previously seen such from the British government telling me that some breed of dog was now banned even though I don't own a dog and also live in Germany)…

… but none of that's what's importantly wrong.

Cost effective? It's an auction, each ad in isolation may be fair (but there's reason even then to be suspicious), but in aggregate the ad sector is an all-pay auction.

There's a massive over-supply of solutions because all the startups chase the same ideas at about the same times, and the only one of them to get big is the one that pays enough to the gatekeepers of eyeballs to win the all-pay auction bidding for mindshare.

If everyone stopped advertising, the knowledge of solutions would still diffuse, the winner would be so by word of mouth. The difference is that the 1200 "trusted partners" on all the GDPR popups wouldn't collect rent on advising people on the best strategy for selling their user's privacy and battery life and mobile data allowance for money that those users never get to see, and the people buying those eyeballs wouldn't be wasting their VC runway making something other than the product.

The fact that your Facebook ads are worse is probably because you're in the EU. I'm in the US, and I am getting fairly relevant ads for Broadway shows, data infrastructure products, discounted hotel packages, and climbing gym subscriptions - things that I am actually considering purchasing. And we haven't even brought up intent-based ads (Google search).

Word of mouth benefits incumbents. Advertising at least enables newcomers to temporarily burn money to gain mindshare, while “slow diffusion” will lock society into a “nobody ever got fired for buying IBM” state forever.

The only way this should happen is if it’s a fake arthritis treatment meant to detect doctors who learn about treatments from advertising instead of legitimate sources, so they can be prevented from practicing medicine.

[yunyu]

What are legitimate sources in your definition? Should physicians be expected to spend all their free time reading every single study in every medical journal or conference, even for niche areas that they don't usually encounter? Should the average diabetic/arthritic patient need to obsessively pore over academic reports to stay informed about their condition? Should advertisers be banned from sponsoring journals or conferences? This is an extremely ill informed line of reasoning.
