The main reason why leading world companies create accounts in social networks is to attract traffic to landing pages and websites. YouTube's video hosting by the number of search queries is second only to the Google search engine, and you can attract some of this huge traffic flow to your site / landing page by simply posting your video (and related links to your web resources) on this hosting.
The Direct Selling Association (DSA), a lobbying group for the MLM industry, reported that in 1990 only 25% of DSA members used the MLM business model. By 1999, this had grown to 77.3%. By 2009, 94.2% of DSA members were using MLM, accounting for 99.6% of sellers, and 97.1% of sales. Companies such as Avon, Electrolux, Tupperware, and Kirby were all originally single-level marketing companies, using that traditional and uncontroversial direct selling business model (distinct from MLM) to sell their goods. However, they later introduced multi-level compensation plans, becoming MLMs. The DSA has approximately 200 members while it is estimated there are over 1,000 firms using multi-level marketing in the United States alone.
MLMs have been made illegal in some jurisdictions as a mere variation of the traditional pyramid scheme, including in mainland China. In jurisdictions where MLMs have not been made illegal, many illegal pyramid schemes attempt to present themselves as MLM businesses. Given that the overwhelming majority of MLM participants cannot realistically make a net profit, let alone a significant net profit, but instead overwhelmingly operate at net losses, some sources have defined all MLMs as a type of pyramid scheme, even if they have not been made illegal like traditional pyramid schemes through legislative statutes.
