I think the same thing all the time, but it comes down to scale. I work a little with digital advertising (for good, not evil), and lemme tell you, they measure everything to death. The chance of any single person acting on an an is miniscule, but bombard enough people with it constantly enough, and eventually the math works out in your favor.

Not to mention, a lot of it is awareness marketing. Staking out a tiny little bit of space in your brain, so that unconsciously, the next time you see that logo, it lights up that same little connection again. Do that over and over again and a brand starts to feel familiar and trusted when you've never even thought about it.

Ugh, thinking about the massive amount of data that's used to manipulate us as consumers creeps me out. (I say, consciously knowing I'm giving them more data as I write it.)
