Wikipedia (/ˌwɪkɪˈpiːdiə/ (listen), /ˌwɪkiˈpiːdiə/ (listen) WIK-ih-PEE-dee-ə) is a multilingual online encyclopedia with exclusively free content and no ads (though donations are accepted), based on open collaboration through a model of content editing using web-based applications such as web browsers, called wiki. It is the largest and most popular general reference work on the World Wide Web, and is one of the most popular websites by Alexa rank as of April 2019. It is owned and supported by the Wikimedia Foundation, a non-profit organization that operates on money it receives from donors to remain ad-free.
Wikipedia was launched on January 15, 2001, by Jimmy Wales and Larry Sanger. Sanger coined its name, as a portmanteau of wiki (the Hawai’ian word for “quick”) and “encyclopedia“. Initially an English-language encyclopedia, versions in other languages were quickly developed. With 5,861,248 articles,[notes 3] the English Wikipedia is the largest of the more than 290 Wikipedia encyclopedias. Overall, Wikipedia comprises more than 40 million articles in 301 different languages and by February 2014 it had reached 18 billion page views and nearly 500 million unique visitors per month.
In 2005, Nature published a peer review comparing 42 hard science articles from Encyclopædia Britannica and Wikipedia and found that Wikipedia’s level of accuracy approached that of Britannica, although critics suggested that it might not have fared so well in a similar study of a random sampling of all articles or one focused on social science or contentious social issues. The following year, Time magazine stated that the open-door policy of allowing anyone to edit had made Wikipedia the biggest and possibly the best encyclopedia in the world, and was a testament to the vision of Jimmy Wales.
Wikipedia has been criticized for exhibiting systemic bias, for presenting a mixture of “truths, half truths, and some falsehoods”, and for being subject to manipulation and spin in controversial topics. But by 2017, Facebook announced that it would help readers detect fake news by suggesting links to related Wikipedia articles. YouTube announced a similar plan in 2018.
Wading River is a hamlet and census-designated place (CDP) in Suffolk County, New York, United States, on the North Shore of Long Island. As of the 2010 census, the CDP population was 7,719. It is adjacent to Shoreham and shares a school district.
Most of Wading River lies within the Town of Riverhead, but a small portion is in the Town of Brookhaven. The name of the hamlet comes from the original Algonquian name for the area, Pauquaconsuk, meaning “the place where we wade for thick, round-shelled clams”. “Wading in the River” or Wading River was adopted by the first English colonists.
