In the United States, a new law proposal called The Combating Online Infringement and Counterfeits Act (COICA) was introduced last week, and there will be a hearing in front of the Judiciary Committee this Thursday.
If passed, this law will allow the government, under the command of the media companies, to censor the internet as they see fit, like China and Iran do, with the difference that the sites they decide to censor will be completely removed from the internet and not just in the US.
Please see the following article from the Huffington Post for more information.
