It's aggravating, sure, but ads serve multiple purpose. Sometimes people are entertained by ads, seeing it as a way to sample what's available in the world. Showing ads help establish branding for a company or product. By seeing multiple ads for the same thing, familiarity increases, and with that, the chance of the person choosing the thing in the future. Also companies compete on available ad spots. Sometimes buying an ad space means that your competitor has not bought that ad space. With that said, I block advertisements everywhere I can, and honestly, I feel like this should be the norm. Barely legal psychological warfare. Edit: I'd like to also add something about "I already know what I want". People feel like they do, but they have a lot more going on in their heads than they think. For example, a more attractive alternative might exist that you don't know about. Or you could spot a discount on something that's not urgent, but important - with a limited budget, you might prioritize that instead of your original goal.
