Wiki:Censorship by Google
Google and its subsidiary companies, such as YouTube, have removed or omitted information from its services to comply with its company policies, legal demands, and government censorship laws. Google's censorship varies between countries and their regulations, and ranges from advertisements to speeches.
Numerous governments have asked Google to censor what they publish. In 2012, Google ruled in favor of more than half of the requests they received via court orders and phone calls. This did not include China and Iran who had blocked their site entirely.
