I would not be shocked to learn that advertising for a specific product or event is not particularly effective. However, I'm inclined to believe it has a huge effect on overall brand recognition.

Let's say you go to Amazon to buy a roll of toilet paper. How do you choose from the literally hundreds of options? You could spend a day of your life reading reviews, and trying to parse which ones are fake. Or you could buy the toilet paper from Scott because you recognize the brand.

As I see it, buying brand advertising is a lot like buying an expensive suit. It's not that the suit makes you more productive, but it is a sign of professionalism, and—frankly—of wealth. If a brand is advertising everywhere, you know they aren't a fly-by-night company, and their products likely meet some standards of quality.
