What keeps BMs (brand marketers) up at night? Maybe it's mosquitos or constipation, though I doubt it's the latter because everyone knows that a good BM is the result of eating lots of fiber. And I doubt it's the former, because, rather than sweet blood, most BMs' veins pump, you guessed it, Coca-Cola. What keeps them up at night is the thought that nobody is watching their super-slick, multi-million dollar TV ad campaigns.
