What is the full form of "MLM"?

Multilevel marketing (MLM) is a strategy some direct sales companies use to encourage existing distributors to recruit new distributors who are paid a percentage of their recruits' sales. The recruits are the distributor's "downline." Distributors also make money through direct sales of products to customers. Amway, which sells health, beauty, and home care products, is an example of a well-known direct sales company that uses multilevel marketing.
