In The Future of Ideas, Lawrence Lessig explains how the Internet revolution has produced a counterrevolution of devastating power and effect. The explosion of innovation we have seen in the environment of the Internet was not conjured from some new, previously unimagined technological magic; instead, it came from an ideal as old as the nation. Creativity flourished there because the Internet protected an innovation commons. The Internet’s very design built a neutral platform upon which the widest range of creators could experiment. The legal architecture surrounding it protected this free space so that culture and information–the ideas of our era–could flow freely and inspire an unprecedented breadth of expression. But this structural design is changing–both legally and technically.
