Here is the list of the Top 100 MLM companies in the World by Direct Selling News. They are ranked based on the 2011 Sales revenue generated by the MLM companies. There are currently 11 MLM companies who have crossed the 1 billion dollar mark.
The point of me listing the top 100 MLM companies in the world, is not to compete with fellow network marketers, see whose company is ranked higher than the other. But, is to show the amount of products that have moved through the MLM channel of distribution.
