Is it really unclear? If you had never heard of a product, you would much less likely purchase it. If Coke stopped advertising today, they’d start a very slow but real loss of market to it’s competiton, be it Pepsi or whatever. Note that a LOT of advertising is not for you. It’s for the corporate buyer at name your favorite restaurant so that they think that they’ll get more consumers in the door because they have Coke products, as opposed to some other brand.
Played for a couple years but it got tiresome. It’s still on my phone but I haven’t launched it in at least a year.
