Lessig tells the story of his book, Free Culture:
After persuading the publishers, Penguin Publishers, to allow his book to be made available under the Creative Commons license, something incredible happened:
After 24 hours, the book had been made available under 9 separate formats (txt, pdf etc).
After 36 hours, an audio version of the book had been announced.
After 48 hours, a wiki had been launched by Aaron Schwartz for others to build on and add to.
After 1 week: 200 000 copies of the book had been downloaded.
