Stop Online Piracy Act is a bill that was introduced in the U.S. House of Representatives in October 2011 by Lamar Smith (R-TX). This Act would allow the Department of Justice and copyright holders to seek court orders against websites accused of copyright infringement that would prevent online ad networks and payment facilitators from doing business with those websites. Opponents in this bill believe that this is Internet censorship. Google co-founder Sergey Brin, Twitter co-founder Jack Dorsey, PayPal co-founder Elon Musk, and Yahoo! co-founder Jerry Yang oppose the bill. Their letter will appear as a paid ad in The New York Times, The Washington Post, and other newspapers.
