Answer:
Marketing creates a need that an individual might not have acknowledged in his life before. Once he is introduced, he now feels the need to fulfill the need and consume the product that is being marketed. If the product satisfies, the sense of happiness increases and vice versa.
If that needs is common, an individual might be open about consuming that product and if is not, he might not share it with his peers because he feels uncomfortable.
An individuals needs are what makes him unique and different. Everyone cannot have similar needs or wishes. Media plays a important role in developing needs and wishes of a person and also shows a way of fulfilling those needs. Media is not a mirror, it is a black hole.
