At one time, definitely. Now though? We all carry around all of humanity's collective knowledge in our pockets. If you need a solution to a problem you have, if you need a plumber, if you need a new car... you an get unlimited information for the asking.
I don't remember the last time I responded to an advertisement. If I need things, I search Amazon/Etsy/local retailer apps or just go to a store. If I need contractors, I check local review pages to find good ones or just call ones I've used before. And some of that I guess you could call ads, but I mean in the traditional sense, where someone has paid to have someone put a product in front of me that I wasn't already looking for? Nah. Never happens.
