DEFINE MLM MARKETING BY WIKIPIDIA..

Multi-level marketing (MLM), (also called network marketing[1][2][3][4][5], direct selling[6][3], referral marketing[7], and pyramid selling[8][9][10][11][12]) is a term that describes a marketing structure used by some companies as part of their overall marketing strategy. The structure is designed to create a marketing and sales force by compensating promoters of company products not only for sales they personally generate, but also for the sales of other promoters they introduce to the company, creating a downline of distributors and a hierarchy of multiple levels of compensation in the form of a pyramid.

The products and company are usually marketed directly to consumers and potential business partners by means of relationship referrals and word of mouth marketing.[13]

MLM companies have been a frequent subject of controversy as well as the target of lawsuits. Criticisms have focused on their similarity to illegal pyramid schemes, price-fixing of products, high initial start-up costs, emphasis on recruitment of lower-tiered salespeople over actual sales, encouraging if not requiring salespeople to purchase and use the company's products, potential exploitation of personal relationships which are used as new sales and recruiting targets, complex and sometimes exaggerated compensation schemes, and cult-like techniques which some groups use to enhance their members enthusiasm and devotion. Not all MLM companies operate the same way, and MLM groups have persistently denied that their techniques are anything but legitimate business practices.
