Discuss the advantages and disadvantages of advertising

What will be an ideal response?

Advertising can reach masses of geographically dispersed buyers at a low cost per exposure, and it enables the seller to repeat a message many times. Beyond its reach, large-scale advertising says something positive about the seller's size, popularity, and success. Because of advertising's public nature, consumers tend to view advertised products as more legitimate. Advertising is also very expressive; it allows the company to dramatize its products through the artful use of visuals, print, sound, and color.
Advertising also has some shortcomings. Although it reaches many people quickly, advertising is impersonal and lacks the direct persuasiveness of company salespeople. For the most part, advertising can carry on only a one-way communication with an audience, and the audience does not feel that it has to pay attention or respond. In addition, advertising can be very costly.
