In the business world, marketing of ideas, services or products is the basic and simplest task a businessman does. Simple it may be, yet competition is very stiff especially for products of the same type and category. Medicine for instance, there are several pharmaceuticals and laboratories that manufacture the same line of drugs and medical representatives compete in order to market their products to the doctors, hospitals and clinics. One state-of-the-art marketing tool is the use of projectors for a sophisticated product presentation. I have a colleague in college, a medical representative, who uses a canon projector in her product presentations in the hospitals and clinics. I bet she is able to meet her monthly quota out of her high tech presentations and natural charm. :)
