How do you think those drinks get there? Beverage companies are paying for shelf space.

But, if you think ads for drinks don't work, take a look at Pepsi's Project Refresh of 2010, and what happened to their sales. TLDR, Pepsi took it's superb owl ad budget and used it to do community grants instead; sales dropped and a couple years later, Pepsi went back to advertising during the superb owl and stopped doing community grants.
