Censorship by Google is Google's removal or omission of information from its services or those of its subsidiary companies, such as YouTube, in order to comply with its company policies, legal demands, or various government censorship laws. Google's censorship varies between countries and their regulations, and ranges from advertisements to speeches. Over the years, the search engine's censorship policies and targets have also differed, and have been the source of internet censorship debates. This popular search engine has been asked by numerous governments from around the world to censor what they publish. In 2012, flooded with over a thousand requests (court orders and phone calls), Google found in favor of more than half of them. This wasn't including China and Iran who block their site entirely.
