The fact is that majority of brands and products are boring. Being boring is a challenge, because your brand will not be noticed. You are not competing against the other products and brands in category, you are competing of mindspace of your consumer which is increasingly filled with Netflix, Snapchat and other way more interesting things than you brand.
The main role for advertising is to sell more products and how you do it is by making your product more interesting, desirable and thus noticed. Rational arguments don´t really work. Every smoker knows that he would need to quit. You know that you should hit the gym. And you know that carrots are healthy, but you still choose to munch on chips because they just taste good.
This campaign from few years back is a brilliant example of the true power of advertising. You have a great product, but it has an image problem. You fix it by going totally overboard. You appeal to heart. You beg, borrow and steal from other categories. You are bold. You make that product differentiated and interesting. If your category is boring, you reframe your whole category. You do what you are supposed to do:
If advertising industry has identity problem right now, it is because we have lost our focus on making the brands we work with desirable. We have gone too deep in rabbit hole of championing social causes or doing unnecessary technological innovations, that we have forgotten why we exist in the first place.
