Multilevel Marketing is big business. There are dozens of companies (including Infotrax) that sell products and services to MLMs new and old. My company has been supporting companies in the industry for decades. I have seen a lot of companies start: some fail some succeed beyond their wildest expectations, and many others fall somewhere in between.
Evolving distributor motivations

Just as companies are started by entrepreneurs, the first distributors who join a company are themselves entrepreneurs. However, as a company becomes more established, it attracts distributors who are more conservative, more risk adverse.
