In barely six years, a small group of young, ambitious programmers in Silicon Valley built an $11.5 billion business out of the ashes of a failed podcasting company.

This is a tale of betrayed friendships and high-stakes power struggles as the four founders???Biz Stone, Evan Williams, Jack Dorsey, and Noah Glass???went from everyday engineers to wealthy celebrities, featured on magazine covers, Oprah, The Daily Show, and Time???s list of the world???s most influential people.,Bilton???s exclusive access and exhaustive investigative reporting???drawing on hundreds of sources, documents, and internal e-mails???have enabled him to write an intimate portrait of fame, influence, and power. He also captures the zeitgeist and global influence of Twitter, which has been used to help overthrow governments in the Middle East and disrupt the very fabric of the way people communicate.
