The Stop Online Piracy Act (SOPA) aims to strengthen protections for US intellectual property but has generated controversy over its impact on freedom of expression and the open Internet. While supporters believe SOPA will safeguard US innovation, jobs, and revenues, opponents argue it could undermine the dynamic nature of the Internet and innovation. A vote on SOPA was postponed in January 2012 amid protests from websites and technology firms. The bill's proponents are now re-examining its language to address concerns raised.
