The online protest against SOPA and PIPA involved a diverse array of websites, ranging from large platforms like Wikipedia to smaller independent sites. This unprecedented action took place in January as the U.S. Congress was holding hearings on both bills, which were designed to combat online piracy but were criticized for their broad implications regarding internet regulation and free speech. Websites blacked out their content, replacing it with messages warning users about the legislation, effectively educating millions about the risks posed by the proposed laws. Users were encouraged to contact their representatives and express their opposition to the bills.

SOPA sought to allow for greater enforcement against websites accused of infringing on copyright, which would have led to potential over-blocking and censorship. Similarly, PIPA would have provided mechanisms for court orders against foreign-based websites, but critics worried it would lead to diminished due process for online entities. As a response to this growing concern over internet governance and freedom of expression, the protest galvanized a vast number of internet users and entities together in solidarity.

The massive participation on sites like Google, where the logo was altered to highlight the issue, demonstrated the internet community's unity on the matter. Many users were shocked at the potential reach of government involvement in online content, prompting a significant public outcry against the bills. The response from Congress and the broader community was immediate, leading to reconsideration of both SOPA and PIPA as a result of this protest, marking a pivotal moment in the ongoing debate over internet regulation.
