The ads probably get to you subconsciously anyway, IIRC there are studies done by psychology experts (some of them also work for the ad industry) that explains the presence of random ads. For one thing, if you're suddenly in the market for a truck, you'll see the brand that was in an ad a long time ago and you think "Oh yeah I've heard of Ford, never heard of Isuzu, let's look at the Ford much closer.". Even a tiny nudge that the ad did helps, when selling to millions. Obviously a truck is a big purchase, and you individually probably would do more research, but the nudge applied to millions might move the needle in the heads of a few dozen people.
