Heck the yoga app I use I saw through a mobile ad. Same deal for the fitness app I use (BodBot, awesome app, check it out!)
I've gotten onboard Kickstarters from ads, and I've bought keto cereal from an ad I saw.
99.999% of most ads I ignore, but sometimes ads are really well targeted and actually show me something I want.
(None of these ads were on a tv in any way...)
