The Google web search engine is the company's most popular service. According to market research published by comScore in November 2009, Google is the dominant search engine in the United States market, with a market share of 65.6%.[111] Google indexes trillions of web pages, so that users can search for the information they desire, through the use of keywords and operators. Despite its popularity, it has received criticism from a number of organizations. In 2003, The New York Times complained about Google's indexing, claiming that Google's caching of content on their site infringed on their copyright for the content.[112] In this case, the United States District Court of Nevada ruled in favor of Google in Field v. Google and Parker v. Google.[113][114] Furthermore, the publication 2600: The Hacker Quarterly has compiled a list of words that the web giant's new instant search feature will not search.[115] Google Watch has also criticized Google's PageRank algorithms, saying that they discriminate against new websites and favor established sites,[116] and has made allegations about connections between Google and the NSA and the CIA.[117] Despite criticism, the basic search engine has spread to specific services as well, including an image search engine, the Google News search site, Google Maps, and more.
