I only produce one type of car, the Model T, and one color, black. What kind of marketing concept is this, and what are the characteristics of this concept?

This is a marketing concept in which the manufacturer can meet the needs of the consumer at the lowest cost, in the shortest time, and in the most direct way, in order to achieve the fastest profit when there is a lack of competitors in the market and the consumer's awareness of the product and its requirements have not yet been raised.

In the absence of rivals, all things are done just to meet the requirements on it, more is a waste of time, a waste of their own time and a waste of consumer time, since the consumer will buy, that red tape can be exempted.

This approach is suitable for monopoly goods, you have an absolute advantage, in this case too much marketing skills but is a snake, you just need to do is to find a place to sit there, start selling things!
