I do not know that there has been written about this area but I think that the best books are the books available e-marketing, this company relies entirely on electronic marketing, learn from them how to bring members to the company and promise them to work for us, and so on.
Ask this and find a distinctive idea is why do not we create wrote about this company?? Is not it a very special and will be considered from the books that would meet a great success, such as Google Adsense, thank you
