When the majority of consumers enters the market, the market reaches its full market potential.

This statement is referring to the concept of market saturation. When the majority of consumers in a given market are actively purchasing a product or service, the market is said to have reached its "full market potential." This means that the product or service has reached its maximum possible sales in that market, given the current conditions.

Here are the steps to understand this concept:

1. Identify the Market: The first step is to identify the market for a particular product or service. This could be a geographical area, a demographic group, or any other group of potential consumers.

2. Understand Consumer Behavior: The next step is to understand the behavior of consumers in this market. This includes understanding their needs, preferences, and purchasing habits.

3. Estimate Market Potential: Based on the understanding of consumer behavior, an estimate of the market potential can be made. This is the maximum possible sales that could be achieved in the market.

4. Monitor Market Penetration: This involves monitoring the actual sales of the product or service in the market. As more and more consumers start purchasing the product or service, the market is said to be getting saturated.

5. Reach Full Market Potential: When the majority of consumers in the market are purchasing the product or service, the market is said to have reached its full market potential. At this point, any further increase in sales would require expanding the market, improving the product or service, or changing the market conditions.
