If you look at Google, you might notice the company has a chosen a black mark as its header. Usually, the header will be something interactive, colorful or relevant to the day. On Wednesday, it represented a call to action for web users to contact their senators and ask them to vote against pending legislation that would shut down websites that post or share pirated content and movies.
The two bills are known as the Stop Online Piracy Act and Protect IP Act and both threaten to shut down websites that enable copyright infringement. Media companies say the passage of the bills could hinder search engines and news aggregators.
In protest of SOPA and PIPA, several popular websites, such as Wikipedia and Reddit, have blacked out their sites for the day, urging readers to contact their representatives.
