20+ year advertising hack, here.
Advertising is made almost exclusively by ad agencies. Ad agencies run on a service model. I.e., you do what your client tells you to.
Your client is always a group of marketers and a brand manager who are all terrified of their bosses—and each other.
The remedy, they feel, is to demand you, the agency they hired, “break through” with content, which today, usually just means annoying the crap out of people, because it’s the only thing all those terrified clients can agree will work.
Which, unfortunately, it does.
Every crap ad starts out awesome, interesting and—hopefully—compelling. An novel ad like that *might* move the needle 5%—or it might move it 0%, which means all that money spent is lost and everyone loses their job.
However, if a really annoying, weird, hack job of an ad that pierces the dumpster fire of a media landscape we all live in will *guarantee* a needle move of 2%, those terrified clients are going with that 100% of the time.
Tl;dr: capitalism
