Wednesday, Jan. 18, marked the largest online protest in the history of the Internet. Websites from large to small "went dark" in protest of proposed legislation before the U.S. House and Senate that could profoundly change the Internet. The two bills, SOPA in the House and PIPA in the Senate, ostensibly aim to stop the piracy of copyrighted material over the Internet on websites based outside the U.S. Critics, among them the founders of Google, Wikipedia, the Internet Archive, Tumblr and Twitter, counter that the laws will stifle innovation and investment, hallmarks of the free, open Internet.
