Multi-Level Marketing (MLM)

I was looking for some info on Multi-Level Marketing this afternoon. (I saw the term on a "about us" page in a networking site; they were saying, "no multi-level marketing, no spam blah blah blah...) Anyway, there are lots of sources about MLM; here are some descriptions and articles...

Once upon a time, multi-level marketing was a legitimate business which provided a way for small companies to get their unique products to consumers in small towns and rural areas which had no access to these products. At this time, the products sold themselves, and the multi-level aspect was a way of giving a small reward to those who had worked hard to build the organization. But the focus was always on the product.

And this is from Wikipedia:
In a typical multi-level marketing or network marketing arrangement, individuals associate with a parent company as an independent contractor and are compensated based on their sales of products or service, as well as the sales achieved by those they bring into the business.

In a legitimate MLM company, commissions are earned only on sales of the company's products. No money may be earned from recruiting alone ("sign-up fees"). Some less legitimate companies produce revenues primarily by attracting new participants or selling them marketing services, as opposed to selling actual products. One must analyze the compensation plan to determine whether participants are paid from actual sales to customers and not from new-recruit bonuses or business support sales.
