The advertisement that is being shown on television is usually about the product. This is in charge of teaching people how the products can be used in their daily lives or even during different situations. The main goal of the advertisement is to show people why they need to have products. Commercials are sometimes meant to be exaggerated so that the emotional impact of the product on people will be stronger than usual.
It is likely that if you would see a product that is being advertised often, you will get curious and you would try it out. If you are happy with the results that the product can give you, you will probably continue purchasing, and this is the primary goal of the company in the first place.
