I’m pretty sure that’s the only thing I’ve bought because I saw an ad online.
So... you're not immune? ;)
Considering how many ads explicitly manufacture desire to fill a previously-nonexistent niche, it's not surprising that they make us unhappy. I was teased recently for turning the volume way down in my car whenever ads came on,* but I do not want to offer that garbage my brainspace, regardless of whether I'm interested in the product.
*Usually I either listen to ad-free Spotify or fast-forward through podcast ads, but I was driving and my friend was in charge of the music. I am deeply grateful that podcast ads are so easily skipped, though.
