Answer:
Cash cows
Step-by-step explanation:
Cash cows are one of the four classifications of the Boston Consulting Group Matrix, the other three being dogs, stars, and questions marks.
Cash cows are products or services that hold a large market share, in a slow-growing industry. They are called cash cows because from the sales they generate, other products or services in fast-growth industries can be financed (for example, question marks or starts).
In other words, cash cows are "milked" to generate operating cash flow that can be either re-invested or distributed as profit.
