I bought YouTube premium because I was sick of seeing their stupid adverts.
"We are a growing lead-gen platform. We have a growing user base of people that are annoyed as hell from our advertisements, so they just pay for subscriptions at other sites to make them go away."
I suspect that the sniper rifle-type ads, where possible due to deep profiling, would spend less of advertisers' money, but would feel incredibly creepy, lowering their efficacy.
That, grammerly and now hello fresh, making me greatly consider premium. Maybe that's Google secret plan, annoy us to death so we subscribe.
It used to be just that melody, set to some screen animations. Then they've added sound effects - button pushes, machinery sounds, to the same ad, I assume in attempt to get my attention.
