In the Brands Death or 2nd part of this chapter David Lubars said "Consumers are like roaches- you spray them and spray them and they get immune after a while", and what does he mean by "spray" and what rhetorical strategy does Naomi use?
What is advertising and metaphoric.
Because the word "spray" is referring to the amount of advertising that the company has to use and the more they advertise the more the consumer becomes immune. So therefore the companies have to advertise more.
