> People know what they need, and have always known

No we don't. I need a better mouse trap, but I already have mouse traps that work, so if you make a better one you need me to find out about it otherwise I'll just buy the same old not so good ones out of habit thinking they work as good as any other one. There are also problems that I don't even know I have. There are a lot of houses with terrible insulation that the owners really need some advertisement to get them to upgrade - it will pay off in just a few years.

These ads do not need to interrupt people's lives to make their cases. If that mouse trap is so good then people who are in the market will discover it by active searching, then spread their discovery. If the new insulation will save people money then that's newsworthy information and will be reported on in information outlets that people subscribe to. The idea that businesses paying to push awareness is the only way people might discover previously unknown products and services is absurd.

If you think the mouse traps work you probably do not need other. Anyway, marketing is not good way to find about flaws of current ways. Because that is not it's focus.

they work but if something else is better.
