Discuss the role of advertising in product differentiation and the intent of advertising in altering the firm’s demand curve.

Answer 1

I am always reminded of Marlboro cigarettes.

Early days: for independent women. Look at all picture icons of ads.

Sales were dismal.
Later days:

sales boomed.

Now you answer your question. If you make the product attractive to the right audience, and they identify with it....

In both cases the makers of the product knew how dangerous smoking was. Lucky for women.
