web search engine

 Google Search, a web search engine, is the company's most popular service. According to market researchcomScore in November 2009, Google is the dominant search engine in theUnited Statesmarket share of 65.6%. Google indexes billions ofweb 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. In this case, the United States District Court of Nevada ruled in favor of Google in Field v. Google and Parker v. Google. 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.

Google Watch has also criticized Google's PageRank algorithms, saying that they discriminate against new websites and favor established sites, and has made allegations about connections between Google and the NSA and the CIA. 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. In early 2006, the company launched Google Video, which allowed users to upload, search, and watch videos from the Internet. In 2009, however, uploads to Google Video were discontinued so that Google could focus more on the search aspect of the service. The company even developedGoogle Desktop, a desktop search application used to search for files local to one's computer. Google's most recent development in search is their partnership with the United States Patent and Trademark Office to create Google Patents, which enables free access to information about patents and trademarks. market, with a published by

One of the more controversial search services Google hosts isGoogle Books. The company began scanning books and uploading limited previews, and full books where allowed, into their new book search engine. The Authors Guild, a group that represents 8,000 U.S. authors, filed a class action suit in aManhattan federal court against Google in 2005 over this new service. Google replied that it is in compliance with all existing and historical applications of copyright laws regarding books.

Google eventually reached a revised settlement in 2009 to limit its scans to books from the U.S., the U.K., Australia and Canada. Furthermore, the Paris Civil Court ruled against Google in late 2009, asking them to remove the works of La Martinière (Éditions du Seuil) from their database. In competition with Amazon.com, Google plans to sell digital versions of new books. Similarly, in response to newcomerBing, on July 21, 2010, Google updated their image search to display a streaming sequence of thumbnails that enlarge when pointed at. Though web searches still appear in a batch per page format, on July 23, 2010, dictionary definitions for certainEnglish words began appearing above the linked results for web searches.

Productivity Tools

In addition to its standard web search services, Google has released over the years a number of online productivity tools. Gmail, a free webmail service provided by Google, was launched as an invitation-only beta program on April 1, 2004,and became available to the general public on February 7, 2007. The service was upgraded from beta status on July 7, 2009, at which time it had 146 million users monthly. The service would be the first online email service with onegigabyte of storage, and the first to keep emails from the same conversation together in one thread, similar to an Internet forum. 

The service currently offers over 7400 MB of free storage with additional storage ranging from 20 GB to 16 TB available for US$0.25 per 1 GB per year. Furthermore, software developers know Gmail for its pioneering use of AJAX, a programming technique that allows web pages to be interactive without refreshing the browser.Steve Ballmer(Microsoft's CEO), Liz Figueroa, Mark Rasch, and the editors of Google Watch believe the processing of email message content goes beyond proper use, but Google claims that mail sent to or from Gmail is never read by a human being beyond the account holder, and is only used to improve relevance of advertisements. One criticism of Gmail has been the potential for data disclosure, a risk associated with many online web applications. 

Google Docs, another part of Google's productivity suite, allows users to create, edit, and collaborate on documents in an online environment, not dissimilar to Microsoft Word. The service was originally called Writely, but was obtained by Google on March 9, 2006, where it was released as an invitation-only preview. On June 6 after the acquisition, Google created an experimental spreadsheet editing program,which would be combined with Google Docs on October 10. A program to edit presentations would complete the set on September 17, 2007, before all three services were taken out of beta along with Gmail, Google Calendar and all products from the Google Apps Suite on July 7, 2009.
