Modern direct selling includes sales made through the party plan, one-on-one demonstrations, and other personal contact arrangements as well as internet sales. Some sources have defined direct selling as: "The direct personal presentation, demonstration, and sale of products and services to consumers, usually in their homes or at their jobs."
Direct selling consists of two main business models: single-level marketing, in which a direct seller makes money by buying products from a parent organization and selling them directly to customers, and multi-level marketing (also known as network marketing or person-to-person marketing), in which the direct seller may earn money from both direct sales to customers and by sponsoring new direct sellers and potentially earning a commission from their efforts.[unreliable source?]
