I wonder always whether the ad buyers genuinely believe that someone is up there to watch an ad, or actually even with extremely low return ratio per money spent they still manage to get measurable more sales in return.

Maybe few times in my life I was remotely considering buying something because of an ad, while 99,99% of them make me switch channels, or mute the TV/radio until they end. I'm ad blind on social media, not to mention I use ad-blockers wherever I can.

To me it's like buying thin air, and how this market is able to get serious companies spent millions on it is beyond me.
