Our stock market probably would not exist, since there would be no major corporations. Without advertising in the media, corporations would not earn enough capital to form and grow because people in different communities would not be able to find out about businesses located elsewhere. Communities would have a limited number of goods and services available, and the theories of supply and demand dictate that a limited supply demands high prices. We would pay high prices for goods and services that might not be the best quality. Without advertising, we probably would only buy what we need, not what we want.
Mass media prevail in all aspects of our lives.
It is hard to determine exactly what our lives would be like without them, and, at this point, we would be foolish to think we could exist without them.
