Volume is the biggest problem, sure. Content is a close second. I was flabbergasted last time I was in the USA. Ads have barely any relation to what they’re selling.
A poster for shoes features a full-body shot of a half-naked model, the shoes barely visible with the whole poster within your visual field at once.
Ads for beer, travel agencies, clothes and antidepressant medicine, which should be illegal to advertise, by the way, are indistinguishable from each other: just a few happy 20-somethings in a nonspecific late afternoon outdoors setting.
A bunch of ads I saw I don’t even know what they were for, they just had hot young people and logos for companies I never heard of. No text, no nothing.
Several ads purporting to sell an “experience” when they were for the most mundane, use-it-on-autopilot products you’ve ever heard of. The products were so forgettable I can’t remember an actual example, but picture an ad selling you on the wonderful experience of using the new ad-supported monthly coat hanger subscription service and you’ve got it.
Ads for lawyers (something else that should be illegal) were on point though: “hey, do you want money you know you don’t deserve at all but can be argued in bad faith that you do? Hit me up”.
Oh, and everything is perpetually half-off, because the American consumer is apparently too stupid to realize that just means they’re lying about the price.
And the gratuitous association between random brand X and random hot person Y surely also serves a purpose, like subliminally telling your lizard brain that you’ll become like hot person Y, or succeed in mating with them, if you buy brand X. That explains the problem, but does nothing to make it less of a problem.
