On 24 March, 2009 Lawrence Lessig delivered the keynote speech, Getting the Network the World Needs, at the OFC Conference in San Diego, CA. This is a revision of a REMIX talk, distinguishing between parts of the 20th Century that were Read-Only and parts that were Read-Write. His brilliantly delivered thesis discusses how culture prior to the 20th century was essentially read-write, everyone consumed and created the culture interactively. During the 20th century centralization and control of media and distribution transformed our culture to a read only - where creation was almost exclusively the province of professionals and professional distribution channels (tv, movies, music). He then suggests that the 21st century brings the promise and the demand for building a read-write culture once more, and for moving far beyond the mash-up of the past decade. He also discusses the necessary legal and infrastructural changes needed to accommodate this changed reality. Warner Music has tried to serve a DCMA takedown, based on his inclusion of some music and media clips - despite the obvious and clear "fair use".
