Viral Loop
By Adam Penenberg

HOW TO SUCCEED LIKE FACEBOOK, EBAY, YOUTUBE...AND TUPPERWARE?

Adam Penenberg's new book is VIRAL LOOP: From Facebook to Twitter, How Today's Smartest Businesses Grow Themselves (Hyperion; October 13, 2009; Hardcover; $25.99)

Facebook, Skype, and even Tupperware created something people really wanted, so much so that their customers spread the word about their products for them. After all, what's the sense of being on Twitter if none of your friends are? These companies are prime examples of what journalist Adam Penenberg calls a "viral loop": to use the product, you have to spread it so each user begets more users. Penenberg's game-changing book VIRAL LOOP tells the fascinating stories of the entrepreneurs who first harnessed the potential of this business model. Never before has there been the ability to create wealth this fast, on this scale, starting with so little.
