What are the preexisting MLM companies?

Preexisting MLM (multi-level marketing) companies include well-known brands such as Amway, Herbalife, and Avon. These companies operate by recruiting individuals to sell products directly to consumers while also encouraging them to recruit others, creating a hierarchical structure of distributors. Other notable MLMs include Mary Kay, Tupperware, and Pampered Chef. Each of these companies has built a substantial network of independent sales representatives who earn commissions based on their sales and the sales of their recruits.
