You can't ignore ads, they are all around you, moreover, many ads are effective even if you're not consciously paying attention. Look around your home and life at the products that surround you. You've seen ads for many of them. You've seen famous/important people talk about them.

For example, by the time you buy an automobile of a certain brand, you've probably witnessed a lifetime of ads for that brand.

Ads work on everyone. Some people more than others, some ads more than others, but none of us are immune.
