There's lots of products that people really need and could help improve their lives, but they don't know about the existence of the problem/solution.
For example
"Hey do you have hip pain when walking down the stairs? Turns out this is extremely common and we solved it with this special walking stick. Click here to buy the walking stick"
"Were you an Iraq war veteran who served between 2004 and 2006? Turns out the government owes you money. Click here to get it"
"Do you like Blink 182? Turns out they are actually touring again and they are in your city next weekend. Buy tickets now"
There's tons of stuff out there that would be a win-win transaction, if only ppl knew about it.
> Hey do you have hip pain when walking down the stairs? Turns out this is extremely common and we solved it with this special walking stick. Click here to buy the walking stick"
This is where a forward thinking marketer would say "we have a database of email addresses of people reporting hip problems, how much will you pay me for access to them?", aka what Google did.
>"Do you like Blink 182? Turns out they are actually touring again and they are in your city next weekend. Buy tickets now"
I don't like Blink 182, but there have been many times when a band I would have liked to see was in my city and I didn't find out until too late. LiveNation has a feature to warn you about upcoming concerts but it doesn't work well in my experience.
Honestly, it would be really nice to have actual useful advertising like this, but instead we mostly get abusive and intrusive advertising.
I can not recall a single time in my 28 years on this earth where I have seen an advertisement I deemed useful. It is safe to say that falls in this category, would make homeopaths question it's existence.
Anyway, this argument falls flat in a world where the internet exists. All the world's information is easily accessible out there.
