I'm pretty sure that I haven't seen that sort of ad since the late '80s.
I have seen an ad that informed me of the existence of a product with a certain property, which I had wished existed but didn’t think did, and this led to a purchase of the product being made.
However, I don’t remember the content of the ad, so I can’t be confident that it didn’t also have an emotional appeal to it.
The company in question later did something else I didn’t like, but the added feature (really, the removal of a ubiquitous mis/anti feature) continues to be something I appreciate.
