I teach people how to advertise for a living.
This is how I teach it: an advert is simply the ability to buy a knock on someones front door.
That is literally all you are doing when you buy an advert. All business activity you experience today is an abstraction of business we have already done, I'm sure back in the day people thought door to door sales people were annoying, and I'm sure sometimes they were not.
From a founders perspective, you can take this door knock framework and use it for anything, want to do product research? knock on a door. Want to test a marketing message? Knock on a door. Want to boost sales? Knock on a door.
Adverting done wrong can be very annoying. Thankfully people who advertise incorrectly don't usually last very long, and sadly there are indeed a lot of not great marketing folks out there, but cancer on society... hmmm. This article conflates every kind of commercial outreach with malware, psychological abuse, or brand brainwashing... “zero-sum” and purely wasteful. Ok, but in practice competition drives improvement, and customer choice is central to a functioning market, leading to innovation.
