One of the things that US media frequently mentions is the issue of internet censorship in China. This year, Google got into a row with the Chinese government over Google’s refusal block some of the search results that the Chinese government deems too sensitive for the general public (things got so bad at one point that Google announced it was pulling out of China completely. The company and the government have since reached some type of agreement, though I expect the tensions to arise again in the future).
If you search for Tiananmen square, for example, you get lots of search results about the square’s history, design, annual visitors, etc. However, if you add 1989 to the search, you get a message that Google is not available. If you try to go back to the search page, you get the same message and will have to wait a few minutes for Google’s services to return. On Bing, Microsoft’s search engine, you can search for Tiananmen 1989, but if you click on any result that has ‘protests’ or ‘massacre’ in the description, you get nowhere.
