Are Monopoly Industries Unaffected by Marketing?

Monopoly Industries are Relatively Unaffected by Marketing
Rumbiey Muchenje, Entrepreneur, China
An obvious effect of a monopoly situation (such as in many development countries) is that the marketing and advertising industry slowly become unappreciated. This may affect the investment rates in countries, when an investor wants to pour in resources into a country like that he obviously wants to look at the marketing and advertising area, which in most monopolistic industries not exist.
Another effect is that any multi-national wishing to do business in the country would rather get foreign advertising agencies to work with them, limiting the scope of work for local agencies.
Another effect of industries that are monopolized is that because there is little or no need to market and advertise, the advertising agencies are very limited to fully do what they do best, brand management and development.

Monopoly is Affected by Marketing
Sapna, Professor, India
Monopoly industries ARE affected by marketing to some extent to enhance their market area.
If a product is new in a monopoly market, then the monopoly would be affected by marketing up to a great extent, as for making people aware about the new product.
