More than 115,000 websites engage in an online protest against the Stop Online Piracy Act and the Protect IP Act in the US.[citation needed] The websites involved viewed the laws as infringing on the right to free speech and many of them temporarily shut down in protest.

On January 18, 2012, a series of coordinated protests occurred against two proposed laws in the United States Congress—the Stop Online Piracy Act (SOPA) and the PROTECT IP Act (PIPA). These followed smaller protests in late 2011. Protests were based on concerns that the bills, intended to provide more robust responses to copyright infringement arising outside the United States, contained measures that could possibly infringe online freedom of speech, websites, and Internet communities. Protesters also argued that there were insufficient safeguards in place to protect sites based upon user-generated content.

The Stop Online Piracy Act (SOPA) was a proposed United States congressional bill to expand the ability of U.S. law enforcement to combat online copyright infringement and online trafficking in counterfeit goods. Introduced on October 26, 2011, by Representative Lamar Smith (R-TX), provisions included the requesting of court orders to bar advertising networks and payment facilities from conducting business with infringing websites, and search engines from linking to the websites, and court orders requiring Internet service providers to block access to the websites. The proposed law would have expanded existing criminal laws to include unauthorized streaming of copyrighted content, imposing a maximum penalty of five years in prison.

The PROTECT IP Act was a proposed law with the stated goal of giving the US government and copyright holders additional tools to curb access to "rogue websites dedicated to the sale of infringing or counterfeit goods", especially those registered outside the U.S. The bill was introduced on May 12, 2011, by Senator Patrick Leahy (D-VT) and 11 bipartisan co-sponsors. The Congressional Budget Office estimated that implementation of the bill would cost the federal government $47 million through 2016, to cover enforcement costs and the hiring and training of 22 new special agents and 26 support staff. The Senate Judiciary Committee passed the bill, but Senator Ron Wyden (D-OR) placed a hold on it.
