They don't seek to inform you so much as they seek to inform you that something exists whilst manipulating your emotions to get a particular reaction out of you and millions of other people. This is particularly blatant in AV ads.
The other thing, mainly regarding software ads, is they don't seek to inform you so much as manipulate you whilst tracking your every move to guarantee that the ad was effective. This is particularly blatant with the Google and Facebook ad networks, but pretty much almost any 2-bit ad company you've heard of on the web at least tries to do something similar.
So in the end, advertising has at least two major problems with trying to either 1. manipulate you directly through your emotions or 2. manipulating your computer bandwidth and CPU time to violate your privacy and oftentimes, security.
Regarding #1, there are always going to be people that think they're smart enough, intelligent enough, or logical enough that they will never fall prey to this vector of advertising, and almost universally they are wrong. I don't doubt some few exceptions exist, I just don't think I've ever actually met someone who is an exception, nor am I under any illusions that I am. Your best defense is to cut ads out of your life to greatest extent possible. You'll probably never cut bus ads out of your life, if you at all enjoy city living, but you don't have to let advertisers into your home either.
How do you find out about things after that point? If you are at all social, read any kinds of news sites, invest any money into markets, have any kind of skin in some kind of game, or engage in any kind of recreational activities, you'll have other channels of information. Generally the signal will be of a much higher quality than if you were personally bombarded with advertisements intentionally seeking to cut out a large slice of your overall attention bandwidth every single day.
But I don't hate the concept of advertising. I don't deny being influenced by ads, or even sometimes finding them informative. I just reject being tracked and targeted.
Instead, I get ads for interesting new components on DigiKey or Mouser, or the similar, and I find myself clicking on ads several times a week because I'm genuinely interested in what I see -- it's like a news feed for unusual devices.
Imagine if your Twitter feed was served several tweets at a time embedded in other sites you regularly visit. You could argue it's a distraction, but but it's far from unpleasant. "Personalized ads" work a lot the same way for me.
Advertising is primarily about making you buy a product from a particular company, whether it's a good product or not, whether it's right for you or not.
If it were about letting people know your products then 'Nide' would have "if you want these for cross-training the best show are 'Reebob' Cross2" on the advert for their training shoes.
Advertising is almost orthogonal to informative disclosure.
That a pretty simplistic view. I never said ads are 100% true and want the best for you. Ads are informational as they inform you of the existence of a product and their basic characteristics. Small, well-targeted ads can be the only way someone that's just starting could have to let people know about the existence of their product. They don't hold a gun at you to force you to buy a product, they don't remove competition between companies, they don't prevent third-party review sites from existing. Buying or not buying them is up to each individual.
Advertisers want to make sure their customers don't forget to buy their stuff. This is much easier than actually convincing non-customers to do something new.
Don't let advertising companies fool you. Your entire purpose to them is to be just as valuable as the average slaughterhouse cow
For me, that first number is very, very low. I consume just like a lot of other folks, but its mostly art stuff. I have money in my account mostly because I don't have much I actually want that doesn't take some saving for. Mostly, I think these people just want my information or want me to pass on their advertisements. Clothing wants me to advertise for them with products splattered with their logo. They can go diddle themselves.
Want me to watch ads? Pay me. Have actual ad standards. Stop trying to trick me with "information". Stop trying to trick me with popups. And so on. Until then, back to the diddling.
There's no "better approach".
