ELI5: Why do companies like Redbull and Monster spend so much money on sponsorship and advertising when everyone knows them?

Part of marketing and advertising is to generate impulse desires in consumers. You see a commercial for McDonald's, they talk about a Big Mac, you want a Big Mac, you go out and buy a Big Mac. 

Even if they can't compel you to go out and buy a can immediately, Red Bull and Monster are just trying to keep themselves at the forefront of your mind the next time you're shopping for an energy drink.
