Who introduced MLM?

Multi-Level Marketing (MLM) was popularized in the 1940s and 1950s by companies like California Vitamin Company (Cal-Van) and Amway. While the concept of using a network of distributors to sell products has roots in earlier business models, it was Amway co-founders Jay Van Andel and Rich DeVos who significantly shaped and promoted MLM as a modern business strategy. Their success laid the groundwork for many MLM companies that followed.
